Narrated by Anas (Allah be pleased with him)
Anas (Allah be pleased with him) reported: I did not see Allah's Messenger (may peace be upon him) giving a wedding feast (on the marriage) of any one (of his wives) as he did in the case of (his marriage with) Zainab, for then he sacrificed a goat (on this occasion).
