Silsilat al-Ahadith al-Sahihah

Sayyiduna Anas (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "Whoever among the Muslims plants a tree or cultivates a crop, and then a bird, a human, or an animal eats from it, it will be counted as charity for him."

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: “Any Muslim who plants a tree, then whatever is eaten from it is charity on his behalf, whatever is stolen from it is also charity for him, whatever wild animals eat from it is also charity on his behalf, and whatever birds eat from it is also charity for him. (In short) until the Day of Resurrection, whenever any creature uses it and causes any decrease in it, it is charity on his behalf.”

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "If (such a situation arises that) the Day of Judgment is about to occur and one of you has a small date palm sapling in his hand, if he is able to plant it before the Day of Judgment is established, then he should plant it."
