1.0 Inside Salah

1.1 Its Obligation

Among the prerequisites of salahis covering one's nakedness. This obligation is established by the Qur'an, sunnah and consensus (ijma`).

From the Qur'an : Allah's words, (translated),

"O Children of Adam!Wear your [apparel of] beauty in every place of prayer" [Qur'an 7:31]

i.e. that which covers your nakedness.

From the sunnah : the Prophet (upon him be blessings and peace) said,

"Allah does not accept the salah of an adult woman (i.e. one who has reached puberty) except with a scarf."

[Narrated by : Abu Dawud (Book of Salah, "Chapter : A woman praying without a scarf", p. 101),
Tirmidhi (who classified it as hasan in "Chapter : Allah does not accept the salah of an adult woman without a scarf", p. 50),
Ibn Majah (Book of Menstruation, "Chapter : When a woman passes menstruation, she shall not pray except with a scarf", p. 48),
Al-Hakim (who authenticated it in "Chapter : Allah does not accept the salah of an adult woman except with a scarf", vol. I, p. 251),
Bayhaqi (vol. II, p. 233), and
Ibn Khuzaymah (in his Sahih);
vide Bulugh al-Maram # 221, Sahih Ibn Hibban (Book of Salah).]

From consensus : Numerous scholars have reported consensus on the fact that covering the nakedness is a prerequisite for salah. [See Ibn al-Humam's Fath al-Qadir, vol I, p224 of al-Hidayah with its commentaries.]

1.2 For Men

The nakedness of a man is from below his navel upto (and including) the knee, because of the hadith :
On the authority of `Ata' ibn Yisar, on the authority of Abu Ayyub, who said : I heard the Messenger of Allah (may Allah bless him and grant him peace) say,

"That which is above the knees is [part] of nakedness, and that which is below the navel is [part] of nakedness."
[Narrated by : Daraqutni (p.85) and
Bayhaqi (vol. II, p. 229).]

And, in part of a long hadith : On the authority of Siwar ibn Dawud, on the authority of `Amr ibn Shu`ayb, on the authority of his father, on the authority of his grandfather, that the Messenger of Allah (may Allah bless him and grant him peace) said,

" . . . for that which is below the navel, upto the knee is [part] of nakedness."
[Narrated by Daraqutni. Siwar ibn Dawud has been regarded as a mediocre narrator by `Uqayli, but as trustworthy by Ibn Ma`in and Ibn Hibban. Imam Ahmad said there is nothing wrong with him. The hadith is hasan, inshaAllah.]

It is clear that the navel is not part of the nakedness. However, the knee is included in the nakedness because:

i)A mentioned limit may either be included or excluded, but this matter is one of precaution, and so we rule that it is included.
ii) The knee is the intersection of a bone of the area of nakedness [i.e. the thigh] with another that is not [i.e. the shin], so that the lawful and the prohibited are combined therein and therefore cannot be differentiated. Further, if the knee is left uncovered, there is a danger of the thigh being exposed, and hence covering the knee can also be considered necessary to ensure covering of the thigh.
Strictly speaking, (ii) is really the reason that makes this matter one of precaution.
(iii) The hadith of Siwar ibn Dawud starts outby saying 'that which is below the navel,' which is an expression of generality (sighat al-`umum), indicating that everything below the navel, upto the feet, would be included. The next part of the statement, 'upto the knee' specifies the knee as the limit, and hence everything beneath the knee is excluded, but the knee itself remains included.
As for the hadith : On the authority of `Uqbah ibn `Alqamah, on the authority of `Ali, who said : the Messenger of Allah (may Allah bless him and grant him peace) said, "The knee is [part] of the nakedness."
[Narrated by Daraqutni]
it contains a weak narrator, and may not be used as a proof, although it may be used for substantiation.

1.2.1: It is disliked for a man to pray with his shoulders bare, for the Prophet (may Allah bless him and grant him peace) has said,

"None of you must pray in a single garment of which no part comes over his shoulders."
[Narrated by : Bukhari and Muslim; vide Bulugh al-Maram #223]

1.2.2: It is forbidden for a man to keep his lower garment below his ankles out of arrogance, and severely disliked / close-forbidden (makruh tahrimi) to do so even without arrogance, for the Prophet (may Allah bless him and grant him peace) has said,

"Allah will not look, on the Day of Resurrection, at that man who lets his lower garment below the ankles out of arrogance."
[Narrated by : Bukhari and Muslim; vide Riyad al-Salihin]

This is especially important during salah, for another hadith says,

"Allah does not accept the salah of a man who drags his lower garment."
[Narrated by :Abu Dawud, with an isnad which is authentic according to the criteria of Muslim; vide Riyad al-Salihin]

1.3 For women

1.3.1 The entire body of the free-woman is nakedness, except for her face and hands.

" The woman is a nakedness, and so when she goes out, Satan raises his glance to her."
[Narrated by : Tirmidhi, in the Chapter on Suckling, on the authority of Ibn Mas`ud (may Allah be pleased with him). He classified it as hasan sahih gharib. Also reported byIbn Khuzaymah; vide Sahih Ibn HibbAn (3.66)]

A woman should not cover her face or hands while in ihram, based on the authentic narration by Tirmidhi prohibiting a woman in ihram from wearing a veil or gloves.Similarly, she should not cover her her face during salah, unless there are stranger-men around and a danger of fitnah. It may be noted that according to Imams Ahmad ibn Hanbal and Dawud al-Zahiri, the hands are a nakedness.

Evidently the head must be covered in salah.We have already quoted the hadith :

"Allah does not accept the salah of an adult woman (i.e. one who has reached puberty) except with a scarf."

1.3.2 It is at least precautionary for a woman to cover the tops of her feet in salah. Umm Salamah, the wife of the Prophet (may Allah bless him and grant him peace), said,

"A woman should pray in a shift that reaches down and covers the top of her feet."
[Narrated by : Imam Malik in his Muwatta' (8.10.37),
Abu Dawud ("Chapter : In how much should a woman pray", p. 101) and
Bayhaqi (vol. II, p. 232).]

Scholars have differed regarding the feet of the woman : are they`awrah in salah, or outside salah, or both or neither? There are differences among the Hanafis themselves, and there exist three authentic opinions in the madhhab :

1) That the feet are nakedness

This is based on the direct implication of the hadith,

"When a girl reaches puberty, it is not appropriate that any of her should be seen, excepting her face, and her hands upto the wrists."
[Narrated by : Abu Dawud; It is a mursal narration at the level of hasan.]

It is also strengthened by the narration that the Prophet (may Allah bless him and grant him peace) was asked, when he mentioned the prohibition of dragging the lower garment, about what women should do with the ends of their garments. He said, 'They should extend them a span.' Umm Salamah said, 'Then, their feet will be uncovered!'He said, 'Then, they should extend them a cubit, not exceeding that.'
[Narrated by : Tirmidhi,who graded it as hasan sahih,
Nasa'i and Abu Dawud, with the words, "then she will be uncovered."]

This opinion was presented as the madhhab of Abu Hanifah by al-Quduri in "Bidayat al-Mubtadi", and is also espoused by al-Jassas in "Ahkam al-Qur'an" and by Qadi-Khan. Similarly, in Sharh al-Aqta`, it is stated, "The authentic [opinion] is that it is `awrah, from the apparent [implication] of the report." [See al-Bunayah, vol. II, p. 63]Of the latter Hanafi scholars, al-Ghunaymi has inclined towards this view in "al-Lubab."The feet are also considered nakedness by Imams Malik, al-Shafi`i and Ahmad ibn Hanbal.

2) That they are not nakedness.

The argument for this is based on two points:

i) If the establishment of the nakedness is by the saying of Allah, the Exalted, (translated), "And let them not show their beauty, except that of it which is apparent," then the foot is not customarily a location of beauty (it may be for a minority, but regulations are set according to the general rule), and thus Allah, the Exalted, has said, (translated), "And let them not strike their feet in order to make known that adornment which they are hiding," i.e. the ringing of anklets, and this conveys that the feet themselves are of the beauty which is apparent. This is fortified by the fact that the Mother of the Believers, `A'ishah, said, commenting on the verse, (translated), "And let them not show their beauty except that of it which is apparent", "the toe-ring, a silver ring which is [placed] on the toes." [Narrated by Ibn Abi Hatim, as quoted by Ibn Taymiyyah in "Hijab al-Mar'ah", p. 17.]

ii) If the establishment is by the Prophet's saying, "The woman is to be covered," along with it being established that some of her body is excluded due to hardship of [avoiding] exposure, then, by analogy, it should necessitate that the feet also be excluded, due to the corroboration of hardship.This is because she would be put to hardship by her foot showing when she walked barefooted or with shoes, for she may not always find khuffs or socks with which to cover them. Along with this, desire is not aroused by looking at the foot such as is aroused by looking at the face, and so if the face is not `awrah, in spite of the plentiful arousal of desire, then the foot is more appropriate to remain uncovered in view of the hardship associated with covering it. [See "Fath al-Qadir" : al-Hidayah with its commentaries, vol. I, p.225, and al-Bunayah, vol. II, p.63.]

This opinion has been reported by al-Hasan from Abu Hanifah.Al-Marghinani graded it as the more authentic opinion in "al-Hidayah", and Ibn al-Humam and al-`Ayni acknowledged this in their commentaries thereof.This view has been presented as the madhhab by latter mutun, such as "Nur al-Idah" and "al-Durr al-Mukhtar". al-Thanvi concluded in "I`la al-Sunan" that it is sounder from the point of rationale.

3) That they are nakedness outside salah, but not in salah.

Ibn `Abidin reported this as one of the authentic views in "Radd al-Muhtar".
It may be noted that Hafiz Ibn Taymiyyah, the Hanbali, also favored this opinion.He says,
"And similar [is the case with] the foot.It is permissible for her to show it [in salah] according to Abu Hanifah, and [this] is the stronger [position], for `A'ishah considered it of the apparent beauty.. . . . So, this is an evidence that women used to show their feet initially, just as they used to show their faces and hands . . . . for they used not to walk in khuffs or shoes.[Moreover], to cover these in [salah] poses a great hardship, and Umm Salamah said, 'A woman should pray in an ample garment which covers the tops of her feet,' and so when she makes sajdah, the bottoms of her feet may show." [Hijab al-Mara'ah wa-Libasuha fi al-Salah, pp. 17-18]

Some scholars opined that the feet are not nakedness in that she is not required to cover them, but they are nakedness for the purposes of looking and touching, i.e. it is not permissible for stranger men to look at or touch her feet.

2.0 Outside Salah

2.1 Its obligation

It is obligatory upon every sane adult to cover his / her nakedness outside salah, from himself, as well as from others for whom it is not lawful to look at his nakedness. Excepted from this are cases of necessity, such as medical treatment, for which it is permissible for him/her to expose such portion of his/her nakedness as is necessary.Similarly, it is permissible for him to expose it for istinja', bathing, answering the call of nature and the like if he is alone to the extent that nobody can see him. It is not permissible to look at the nakedness of a man or a woman, whether attached to the body or severed.

The Prophet (may Allah bless him and grant him peace) has said,

"A man shall not look at the nakedness of [another] man, nor shall a woman look at the nakedness of [another] woman."
[Narrated by : Muslim (in Kitab al-Hayd),
Tirmidhi, who rated in hasan gharib sahih,
Ibn Majah,
Ahmad]

And, the Prophet (may Allah bless him and grant him peace) told Mu`awiyah ibn Haydah,
"Protect your nakedness [from all] except from your wife and your slaves."
. . . .
He said,
"How about if one of us is alone?"
The Prophet (may Allah bless him and grant him peace) replied,
"It is [even] more appropriate that modesty be shown for Allah than for people."
[Narrated by :Abu Dawud,
Tirmidhi, who graded it hasan,
Ibn Majah,
Ahmad]

2.2 For Men

The nakedness of the man outside salah is what is between his navel and his knees, based on the evidences we have already mentioned. It is permissible for other men or women to look at anything beyond that, provided there is immunity from temptation, although according to Imam Abu Hanifah, a woman may not look at a man's belly or back. [al-Hidayah] In any case, men should not leave their chests or backs exposed if there is a danger of their being seen by women and of fitnah ensuing subsequently.

The thigh is a nakedness, and hence Muslim men may not, in public, wear shorts which expose the thighs.

The Prophet (may Allah bless him and grant him peace) has said,
"Cover your thigh, for the thigh is [part] of the nakedness."
[Narrated by :Tirmidhi, who graded it as hasan, and also by
Abu Dawud, Ahmad, Malik and Ibn Hibban.
Similar narrations are also narrated by Ahmad, and by Tabarani in "al-Mu`jam al-Kabir."
Tirmidhi also narrated, "The thigh is a nakedness" and graded it hasan gharib. Bukhari quoted this as ta`liq.]

2.3 For Women

The fundament here is the words of Allah the Exalted, (translated),

"And let [the believing women] not reveal their beauty, except that of it which is apparent, and let them clasp their scarves over their bosoms.And, let them not reveal their beauty except to their husbands, or their fathers, or their husbands' fathers, or their sons, or their husbands' sons, or their brothers, or their brothers' sons, or their sisters' sons, or their women [i.e. Muslim women], or their slaves, or male servants free of desire, or children who have no sense of the shame of women's nakedness." [Qur'an, 24:31]

2.3.1 If she is in the presence of stranger-men (ajnabiyy, i.e. non-mahram men, viz. men other than her permanently-non-marriageable male relatives, such as father, brothers and sons.), or non-Muslim women, then her nakedness is all her body, except for her face and palms. This is also the view of Imam Malik, and one of the views of Imam al-Shafi`i.Ibn `Abbas said that the 'apparent beauty' referred to in Allah's saying, (translated),

"And let them not expose their beauty, except that of it which is apparent."
is antimony and a ring, (i.e. the face and the hands).
[Narrated by :Tabari, Bayhaqi, Ibn Abi Shaybah, Abdur-Razzaq, Tahawi.It has a solid chain.]

And, we have already mentioned the hadith,
"When a girl reaches puberty, it is not appropriate that any of her should be seen, excepting her face, and her hands upto the wrists."

Thus, the hands and face are not nakedness, and it is lawful to look at them if one is immune from temptation.It is worth pointing out this does not grant a license for indiscriminate looking, for one will generally not know whether or not one will be allured by a woman's looks before one has looked at her.In fact, even accidental glances should be brought in check as soon as one realizes them, for the gaze is one of Iblis' poisoned arrows.

Jabir (may Allah be pleased with him) said, "I asked the Prophet (may Allah bless him and grant him peace) about an accidental look, and the he told me to avert mygaze."
[Narrated by :Muslim]

It is not lawful to touch a woman's face or hands, even if one considers oneself secure from lust. [al-Hidayah]

"The hand of Allah's Messenger did not touch any woman's hand except the hand of that woman his right hand possessed."
[Narrated by : Bukhari]

And, it is reported that Prophet (may Allah bless him and grant him peace) said,
"It is better for any of you that an iron spike be rammed into his head than that he should touch a woman who is not lawful to him."
[Narrated by : Bayhaqi and Tabarani]

The head and hair must be covered, without any disagreement.There is ijma` (consensus) of the scholars on this, and hence any claim to the contrary is a bid`ah.That there is support for the bid`ah from a handful of contemporary individuals is of no consequence, because the ijma` was enacted prior to that, and also because of the clear evidences the dissenters have contradicted. Allah says, (translated),

"And let [the believing women] not reveal their beauty, except that of it which is apparent, and let them clasp their scarves over their bosoms."

The application of this verse to covering the head is twofold:

1. Women are prohibited from revealing their beauty, and the hair is certainly a site of beauty. The exception from covering (viz. for that beauty which is apparent) does not apply to the head or hair, because of the lack of any evidence to indicate it. The phrase 'that which is apparent' is mujmal (not of well-defined import), and requires specification (bayan), which is provided in the hadith in the form of clarification that it refers to the hands and the face. No such specification exists to exclude covering of the head.
   
2. Women are commanded to clasp their scarves over their bosoms, i.e. to cover their chests and necks with the scarves, in addition to the head - as opposed to merely covering the head while leaving the neck and chest exposed as was the practice of women of Jahiliyyah. [Narrated by Ibn Abi Hatim]

As for the claim that one could cover one's neck and chest, but leave the head exposed, this is inadmissible on at least two counts:

1. The word used in the verse is khumur, plural of khimar, which is a head covering. [Tafsir Ibn Kathir, Tafsir Ruh al-Ma`ani] If a piece of cloth is used for covering some other part of the body, it is not a head covering. Should it be contended that it is still, in essence, a head covering being put to another use, we shall respond that this is even further-removed from acceptability. Were it to be true, it suggests redundancy and vainness in the words of Allah, the Exalted, which is inadmissible without disagreement. If it be claimed that any type of covering can be called a khimar, we reply that :
   
   1. the verse talks not about 'khumur' in general, but about 'their khumur', i.e. the women's khumur, and these are the scarves which they were wearing on their heads, and thus it is established that the khimar here is a scarf, and not merely some covering.
      
   2. one cannot look at the Qur'an in isolation; the sunnah must necessarily be consulted to explain, clarify and specify the Qur'an, and the sunnah clarifies that the head is part of the nakedness.
      
2. It is against ijma`

2.3.2 When a woman is alone, or in the presence of Muslim women, her nakedness is that between her navel and her knees.In the presence of mahram men, she must, in addition, cover her belly and back. [al-Hidayah / Fath al-Qadir] The obligation of covering the back is understood from the legislation concerning zihar - a pagan custom in which a man would liken his wife's back to his mother's back to indicate that he no longer had desire for sexual relations her.The Qur'an condemns zihar and stipulates an atonement for it [Qur'an, 58:1-4].This indicates that the wife's back cannot become like the mother's back, and hence that it is not permissible to look at one's mother's back.If the back is a nakedness in this regard, it is fitting, by analogy, that the belly also be.By further analogy, this regulation is extended to other mahram women.

2.3.3 The voice of the woman is not nakedness, because the wives of the Prophet (may Allah bless him and grant him peace) used to speak to the Companions, who used to listen to the regulations of the religion from them.But, it is forbidden to listen to her voice if one fears temptation, even in recitation of the Qur'an.Allah has said, (translated),
"So, do not be soft in speech [O women], lest he in whose heart is a disease should be moved with desire." [Qur'an, 33:32]
See : "Talking to the opposite sex" for more details.

2.3.4A number of scholars have regarded the woman's entire body to be nakedness, without any exception outside of salah. This is one of the views reported from Imam Ahmad ibn Hanbal, and is the view of most of the latter Shafi`i scholars.They view the evidence we have cited as being abrogated, and cite other evidence in their favor, including the practice of the women of Madinah, who covered their entire bodies, with the exception of one or both eyes upon the descent of the verse, (translated),
"O Prophet! Tell your wives, your daughters and the believing women to draw their jalabib (outer garments) over themselves." [Qur'an, 33:59]
Thus, it is at least recommended, and certainly more precautionary, for women to cover their faces, hands and feet also.The word used in the verse, jalabib (plural of jilbab), refers to an outer garment which covers the body completely, and so this is also an argument in favor of covering the face.Also indicating the covering of the face is the verse, (translated),
"And, when you ask them (the Wives of the Prophet) for something you need, then ask them from behind a veil; that is more pure for your hearts and for theirs." [Qur'an, 33:53]
The reasoning here is that if covering the face was a requirement for the Mothers of the Believers, whom Allah has purified [See Qur'an, 33:33], and who talked to the Companions, the best of generations, and that only on matters of religion, then it is more fitting and imperative that women beneath them in station should observe the same, espcially in times of greater moral decadence in society.

Even if the face is not considered a nakedness, it is obligatory to cover it if there is a danger of fitnah. [Radd al-Muhtar]

2.4 The `Awrah of a Child
Al-Thanvi provides the following iinformation :

2.4.1A very small child has no `awrah
[based on a hadith extracted by Bayhaqi. Hafiz al-Zayla`i has mentioned in Nasb al-Rayah that it is not strong.Mufti Muhammad Taqi al-`Uthmani, the editor of I`la al-Sunan mentions that its narrators are trustworthy, although there was some disagreement over one of them.In either case, if there is no authentic narration on a matter, many scholars take by even a weak narration.]

2.4.2Then, when the child starts to have a sense of feeling/shame (which varies from one child to another; some suggested an age of 4 years), the `awrah is the front and back private parts.

2.4.3The `awrah gradually increases with age (according to some) until the age of ten.

2.4.4At the age of ten, it becomes the same as the `awrah of an adult.
This is to accustom the child to covering the `awrah, and is by analogy from the hadith about ordering children to perform salah when they are ten years old.It is not technically a fard on the child, but it is a fard on the parents to enforce it.

2.5 Further, General Regulations
In addition to covering the required parts of the body, the following should also be observed :

2.4.1 The clothes should not be transparent.The Prophet (may Allah bless him and grant him peace) said,
"There are two categories of the inhabitants of Hell that I have not seen: People with whips like the tails of cows, with which they beat people, and women who are clothed yet naked, swaying, and moving out of Allah's religion; their heads are like an inclined camel's hump. They will not enter Heaven, nor smell its fragrance, though its fragrance can be smelt from such and such a distance."
[Narrated by :Muslim, Ahmad, Malik.]

2.4.2 The clothes should not be tight to the extent that they reveal the shape of what they are supposed to be covering.
It is reported that Usamah ibn Zaid was given a piece of Qibtiyyah cloth by the Prophet (may Allah bless him and grant him peace).Later, the Prophet asked Usamah why he was not wearing it.Usamah replied, "O Messenger of Allah!I gave it to my wife for a garment."The Prophet (may Allah bless him and grant him peace) said, "Tell her to make a lining for it, for I fear it may describe her frame."
[Narrated by : Ahmad and Bazzar]

2.4.3 The clothes should not be of those characteristic of the unbelievers
"Whoever imitates a people is one of them."
[Narrated by : Abu Dawud, Ahmad, Bukhari, Tabarani and Bazzar]
"And differ from the allies of Satan with all that you are able."
[Narrated by :Tabarani]

2.4.4 The clothing should not be characteristic of the opposite sex
"The Messenger of Allah (may Allah bless him and grant him peace) cursed those among women who imitate men, and those among men who imitate women."
[Narrated by : Bukhari]

2.4.5 The clothing should not be worn for vanity or fame

2.4.6 Men may not wear silk, gold or silver, with the exception of a silver ring.

2.4.7 Women's clothing should not be such as to attract undue attention to them, as with extremely bright colors.
