Sahih Muslim Book 40, Hadith Number 6837.
‘Abdullah b. Zam’a reported that Allah’s Messenger (may peace be upon him) delivered an address and he made a mention of the dromedary and also made a mention of one (base person) who cut off Its hind legs, and he recited: “When the basest of them broke forth with mischief” (xei. 12). When A mischievous person, strong even because of the strength of a family like Abu Zam’a, broke forth. He then delivered instruction in regard to the women saying: There is amongst you who beats his woman, and in the narration on the authority of Abu Bakr, the words are: He flogs her like a slave-girl. And in the narration of Abu Kuraib (the words are): He flogs like a slave and then comforts his bed with the help of that at the end of the day, and he then advised in regard to laughing of people at the breaking of wind and said: One of you laughs at that which you yourself do.
