Musnad Ahmad 32:1861

Nuh ibn Maymun narrated to us, Abdullah—meaning al-Umari—informed us, from Ishaq ibn Abdullah ibn Abi Talha, from Anas ibn Malik, who said: "I witnessed two wedding feasts for the Messenger of Allah, may Allah bless him and grant him peace, in which there was neither bread nor meat." He said: I said, "O Abu Hamza, what was in them?" He said: "Hays (a dish made of dates, clarified butter, and dried yogurt)."
