‘Abdallah b. Zam'a reported God’s Messenger as saying, “None of you must whip his wife as a slave is whipped and then have intercourse with her at the end of the day.” A version has, “One of you has recourse to whipping his wife as a slave is whipped and perhaps he lies with her at the end of the day.” He then gave them an exhortation about laughing when someone breaks wind, saying, “Why does one of you laugh at what he does himself?” (Bukhari and Muslim.)
