Mishkat al-Masabih 2957

Rafi' b. 'Amr al-Ghifari said:

When I was a boy I used to throw stones at the palm-trees belonging to the Ansar and was brought to the Prophet. He asked, “Why do you throw stones at the palm-trees, boy?” and when I replied that it was to get something to eat he said, “Do not' throw stones, but you may eat anything that falls below them.” Then passing his hand over my head he said, “O God, fill his belly.” Tirmidhi, Abu Dawud and Ibn Majah transmitted it.
