Pearls from the Prophet (peace be upon him)

"Guard yourselves against six things, and I am your surety for Paradise. When you speak, tell the truth; fulfil when you promise; discharge your trust; be chaste in thought and action; and withhold your hand from striking and from taking that which is unlawful and bad."
"You will not enter Paradise until you have faith, and you will not complete your faith until you have love for one another."
"Hell is veiled in delights, and Heaven in hardships and miseries."
The proud will not enter Paradise, nor a violent speaker. Mohammad (peace be upon him) said: "That person will not enter Paradise who has one atom of pride in his heart."
"There are three persons who will not enter Paradise: A habitual drunkard, one who cuts off blood­ties and one who believes in sorcery."
When asked: "What is Islam?" Prophet Mohammad (peace be upon him) said: "Abstinence from prohibitions and obedience to the commandments of Allah."
"Religion is easy, and no one exerts himself too much in religion but it overpowers him; so act aright and keep to the mean and be of good cheer and ask of Divine help in the morning and in the evening and during a part of the night."
The Prophet (peace be upon him) was one day sitting outside among the people when a man came and asked, "What is Iman (Faith)?" He said: "Iman is that you believe in Allah and His angels and in meeting with Him and in His Messengers and that you believe in being raised to life after death."

Then he asked: "What is Islam?" The Prophet (peace be upon him) said: "Islam is that you shall worship Allah and not associate anyone with Him and that you shall keep up prayer and pay Zakat as ordained and fast in the month of Ramadan." The man then asked: "What is Ihsan (Goodness)?" The Prophet said: "That you worship Allah as if you see Him, for you see Him not, surely He sees you."
