It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Allah Almighty has forbidden for my Ummah wine, gambling, wine made from barley or wheat, backgammon or chess, and musical instruments. And Allah Almighty has given me an additional prayer in the form of Witr. Yazid, the narrator, said: By "Qinnin" is meant "Barbat," that is, a musical instrument.

Syedna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: A townsman should not sell on behalf of a villager, do not practice Najsh (artificially inflating prices), no man should bid over his brother’s transaction, no person should send a marriage proposal over his brother’s proposal, and no woman should ask for her sister’s divorce.

Syedna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: When a thief steals, he is not a believer; when an adulterer commits adultery, he is not a believer; when a drunkard drinks alcohol, he is not a believer; when a man commits a great act of plunder and the believers are looking at him, he is not a believer at that time; and when a betrayer betrays, he is not a believer. So avoid these matters, avoid these matters.

Hanish Sanaani says: We fought jihad with Sayyiduna Ruwaifi’ bin Thabit Ansari (may Allah be pleased with him) near a settlement called Jarbah, which was among the western settlements. He stood among us to address us and said: O people! I will say to you only what I heard from the Messenger of Allah (peace and blessings be upon him). On the day of the Battle of Hunayn, he stood among us and said: It is not lawful for a person who believes in Allah and the Last Day to water someone else’s crop with his own water. By this, the Messenger of Allah (peace and blessings be upon him) meant having intercourse with pregnant captive women. Nor is it lawful for anyone, after buying a used captive woman, to have intercourse with her before ensuring her womb is clear; nor to sell the spoils of war before their distribution; nor to ride an animal from the Muslims’ fay’ property until, when he has exhausted it, he returns it; nor to wear a garment from the Muslims’ spoils of war and then, after wearing it out, return it.

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Do not walk in one shoe, do not squat in one lower garment, do not eat with the left hand, do not wrap yourself in a mute cloak, and when lying on your back, do not place one leg over the other. Ibn Jurayj says: I said to Abu Zubair: Does this mean that a person lies down and places his foot on the other knee? He said: Yes. Then he said: A mute cloak is a garment in which the inner and outer part of the lower garment is placed on one shoulder. Ibn Jurayj says: I then said to Abu Zubair: People say that one should not squat in one lower garment when there is exposure? He said: I heard from Sayyiduna Jabir (may Allah be pleased with him) in this way, that a person should not squat in one lower garment. Hajjaj narrated from Ibn Jurayj that Amr's words are that squatting is prohibited when the private parts are exposed.
