Musnad Abu Ya'la al-Mawsili 109:252

Abu Khaythama narrated to us, Rawh narrated to us, Ibn Jurayj narrated to us, he said: Ziyad ibn Isma'il informed me, from Sulayman ibn 'Atiq, from Jabir, he said: When Safiyyah bint Huyayy entered the tent of the Prophet, may Allah bless him and grant him peace, some people were present, and I was present with them so that I might have a share of her. The Prophet, may Allah bless him and grant him peace, came out and said: "Rise from your mother." When it was evening, we were present, and the Prophet, may Allah bless him and grant him peace, came out with his cloak containing about a mudd and a half of 'Ajwah dates. He said: "Eat from the wedding feast of your mother."
