Thabit (may Allah have mercy on him) said: The marriage of Sayyidah Zaynab bint Jahsh (may Allah be pleased with her) was mentioned in the presence of Sayyiduna Anas bin Malik (may Allah be pleased with him), and he said: The Prophet (peace and blessings be upon him) did not give a wedding feast (walimah) on the marriage of any other of his wives like the wedding feast he gave on her marriage; he (peace and blessings be upon him) gave the wedding feast with a goat.
