Musnad Abu Ya'la al-Mawsili 115:10

Khalaf, ‘Abd al-Wahid, and Ibn Hisab narrated to us, they said: Abu ‘Awanah narrated to us, from Qatadah, from Anas, that the Prophet (peace and blessings of Allah be upon him) said: "There is no Muslim who plants a plant or sows a crop, and then a bird, a human, or an animal eats from it, except that it is for him a charity."
