“Avoid the seven destructive sins” They said: “O Messenger of Allah, what are they?” He said: “Associating partners with Allah; magic (sorcery); killing a person whose killing Allah has prohibited except by legal right; consuming usury; devouring the property of an orphan; fleeing from the battlefield; and slandering chaste, innocent, and believing women.”

"Verily, the example of the righteous companion and the evil companion is like that of the carrier of the musk and the blower of the bellows. The carrier of the musk will either give you, or you will buy from him, or you will get a pleasant smell from him, and the blower of the bellows will either burn your clothes or you will get an offensive smell."

"All of my Ummah may be forgiven except those who commit sin openly. One kind of committing sin openly is when one commits something during the night, then the morning comes and Allah has screened it, but he says: 'O So-and-so, last night, I did such-and-such.' Though he spent the night screened by his Lord (none knowing about his sin), in the morning he removes Allah's screen from himself."

"Whoever throws himself from a mountain and kills himself will be in Hellfire, falling down into it and abiding therein eternally forever; whoever drinks poison and kills himself will be carrying his poison in his hand and drinking it in Hellfire, wherein he will abide eternally forever; and whoever kills himself with a piece of iron will be carrying his piece of iron in his hand and stabbing his abdomen with it in Hellfire wherein he will abide eternally forever."

"Shall I inform you of the gravest of the major sins?" He repeated this three times. They said: "Yes, O Messenger of Allah." He said: "Associating partners with Allah and undutifulness to parents." He was reclining and then sat up and said: "And indeed, the false statement." He repeated it so many times that we wished he would stop.

"The major sins are associating partners with Allah, undutifulness to parents, murder, and intentional false oath."
