Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Whoever, out of concern for his Muslim brother's hunger, feeds him until he is full, Allah Almighty forgives him, and He will give him drink until his thirst is quenched."
Abu Ya'la recorded it. Its chain contains a narrator, Bakr bin Khunays, and he is da'if (weak).
