Musnad Ahmad 32:1699

'Affan narrated to us, Hammam narrated to us, from Qatadah, who said: Anas narrated to me: "A tailor in Medina invited the Prophet, peace and blessings of Allah be upon him, for his food. He said: So there was barley bread with rancid fat, and there was gourd in it. He said: So I saw the Prophet, peace and blessings of Allah be upon him, liking the gourd." Anas said: "The gourd has not ceased to be pleasing to me since I saw the Messenger of Allah, peace and blessings of Allah be upon him, liking it."
