Musnad Abu Ya'la al-Mawsili 130:19

Zahmūyah narrated to us, Hushaym narrated to us, from ‘Abd al-‘Azīz, who said: Anas ibn Mālik narrated to us, saying: I sought the Prophet, may Allah bless him and grant him peace, one day, and it was said to me, "He is with a tailor of the family of al-Muṭṭalib." He had invited him, so he answered him. I set out until I entered upon him, and the tailor had prepared food containing pumpkin. I began taking the pumpkin and placing it before the Messenger of Allah, may Allah bless him and grant him peace, because of what I knew of his love for it.
