Musnad Abu Ya'la al-Mawsili 53:9

Ishaq ibn Abi Isra'il narrated to us, Mu'tamir narrated to us, he said: I heard Ibn Abi al-Hakam al-Ghifari saying: My grandmother narrated to me, from the paternal uncle of my father, Rafi' ibn 'Amr al-Ghifari, who said: I was a young boy throwing stones at the palm trees of the Ansar. It was said to the Prophet, peace and blessings of Allah be upon him, "There is a boy here throwing stones at our palm trees," or he said, "throwing stones at the palm trees." He said: So I was brought to the Prophet, peace and blessings of Allah be upon him. He said, "O boy, do not throw stones at the palm trees." I said, "I will eat [from them]." He said, "Do not throw stones at the palm trees; eat what falls." He said: Then he wiped his head and said, "O Allah, fill his stomach."
