Abu Dawud Book 8, Hadith Number 2616.

Chapter : Not known.

Narated By The uncle of AbuRafi ibn Amr al-Ghifari : I was a boy. I used to throw stones at the palm-trees of the Ansar. So I was brought to the Prophet (PBUH) who said: O boy, why do you throw stones at the palm-trees? I said: eat (dates). He said: Do not throw stones at the palm trees, but eat what falls beneath them. He then wiped his head and said: O Allah, fill his belly.
