Jami` at-Tirmidhi Book 47, Hadith 394
The Prophet was asked about Ash-Shafi, so he said: “It is As-Salat, some of it is Shaf (even) and some of it is Witr (odd).”
the Messenger of Allah said: “I have been ordered to fight the people until they say: ‘La ilaha illallah’. So when they say that, their blood and their wealth are safe from me, except for a right, and their reckoning is for Allah.” Then he recited: So remind them – you are only one who reminds. You are not a dictator over them.
“One day, I heard the Prophet while he was mentioning the she-camel and the one who killed her. He said: ‘When their most wicked went forth.’ A strong and mighty man who was invincible among his tribe, like Zam’ah, went forth for her.’ Then I heard him mentioning the women, so he said: ‘One of you should not lash his wife as a slave is lashed, for perhaps he will lay with her at the end of the day.’” He said: “Then he advised against laughing when passing gas, he said: ‘One of you should not laugh at what he himself does.’”
