Chapter 23: The Book of Musaqah
Jabir (Allah be pleased with him) reported Allah' s Messenger (ﷺ) as saying: Never does a Muslim plants a tree except that he has the reward of charity for him, for what is eaten out of that is charity; what is stolen out of that, what the beasts eat out of that, what the birds eat out of that is charity for him. (In short) none incurs a loss to him but it becomes a charity on his part.
Sahih Muslim 1552a
