Musnad Ahmad 33:461

Rawh narrated to us, Ibn Jurayj narrated to us, Ziyad ibn Isma'il informed me, from Sulayman ibn 'Atiq, from Jabir ibn 'Abd Allah, who said: When Safiyyah bint Huyayy entered the tent of the Messenger of Allah, may Allah bless him and grant him peace, some people were present, and I was present with them so that there might be a distribution. The Prophet, may Allah bless him and grant him peace, came out and said: "Get up from your mother." When it was evening, we were present, and the Prophet, may Allah bless him and grant him peace, came out to us with about a mudd and a half of 'Ajwah dates in the edge of his garment, and he said: "Eat from the wedding feast of your mother."
