Chapter 141
Seeking Permission to enter by telling one's Name

874. Anas (May Allah be pleased with him) reported in the course of his famous Hadith pertaining to Al-Isra' (the Ascension) that Messenger of Allah (PBUH) said, "Then Jibril (Gabriel) ascended along with me to the nearest heaven and requested for the gate to be opened. He was asked: `Who is there?' He replied: `Jibril.' He was asked: `Who is with you?' He said: `Muhammad.' Then he ascended to the second heaven and requested for the opening of the gate. He was asked: `Who is there?' He said: `Jibril.' He was asked: `Who is with you?' He replied: `Muhammad.' In the same way he ascended to the third, fourth and all the heavens (i.e., until the seventh). At all of the gates he was asked: `Who is there?' He replied: Jibril.'''
[Al-Bukhari and Muslim]

875. Abu Dharr (May Allah be pleased with him) reported: I stepped out one night and saw Messenger of Allah (PBUH) walking by himself. I began to walk in the moonlit night. He turned round and saw me and asked, "Who is there?'' I replied: "Abu Dharr.''
[Al-Bukhari and Muslim].

876. Umm Hani (May Allah be pleased with her) reported: I went to the Prophet (PBUH) who was taking a bath while Fatimah was screening him. He asked, "Who is there?'' I replied: "I am Umm Hani.''
[Al-Bukhari and Muslim].

877. Jabir (May Allah be pleased with him) reported: I went to the Prophet (PBUH) and knocked at the door (to seek permission). He asked, "Who is there?'' I said: "I''. He repeated, '' I, I?!'' as if he disliked it.
[Al-Bukhari and Muslim].

Commentary: At the doorstep, the visitor should disclose his identity to the host. Secondly, to knock at the door or to ring the door-bell is tantamount to seeking permission to enter the house. When the host comes out, the visitor should first offer him As-Salam.
