Sayyiduna Anas bin Malik (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) came to Khaybar, and Safiyyah bint Huyayy (may Allah be pleased with her) was mentioned. When he (peace and blessings be upon him) was on the road, Umm Sulaym (may Allah be pleased with her) prepared Safiyyah (may Allah be pleased with her) and presented her to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) woke in the morning as a bridegroom. He said: "Whoever has anything, let him bring it." The narrator said: They spread out a leather mat; one brought dates, another cheese, another ghee, another something else, and they mixed them and made hays (a sweet dish). This was the wedding feast (walimah) of the Messenger of Allah (peace and blessings be upon him).
