Musnad Ahmad 32:1899

'Affan narrated to us, Hammam narrated to us, Qatadah narrated to us, from Anas, that Umm Sulaym sent with him a basket containing fresh dates to the Prophet, peace and blessings of Allah be upon him. He said: "So he took a handful and sent it to some of his wives—and he mentioned either twice or three times—then he ate the eating of a man who knows that he desires it."
