Sahih al-Bukhari
Wedlock, Marriage (Nikaah)
Chapter
Narrated Anas:
The Prophet (ﷺ) offered a wedding banquet on the occasion of his marriage to Zainab, and provided a good meal for the Muslims. Then he went out as was his custom on marrying, he came to the dwelling places of the mothers of the Believers (i.e. his wives) invoking good (on them), and they were invoking good (on him). Then he departed (and came back) and saw two men (still sitting there). So he left again. I do not remember whether I informed him or he was informed (by somebody else) of their departure).
