Ibn Hibban

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Prophet (peace and blessings be upon him): "Allah Almighty will say to His servant on the Day of Resurrection: O son of Adam! I was ill, but you did not visit Me. The servant will say: O my Lord! How could I visit You, when You are the Lord of all the worlds? Allah Almighty will say: Did you not know that My such-and-such servant was ill, and you did not visit him? Did you not know that if you had visited him, you would have found its reward with Me? Allah Almighty will say: O son of Adam! I asked you for water to drink, but you did not give Me water. The servant will say: O my Lord! How could I give You water to drink, when You are the Lord of all the worlds? Allah Almighty will say: Did you not know that if you had given water to that person, you would have found (its reward) with Me? O son of Adam! I asked you for food, but you did not give Me food. The servant will say: O my Lord! How could I feed You, when You are the Lord of all the worlds? Allah Almighty will say: Did you not know that My such-and-such servant asked you for food, but you did not give him food? If you had given him food, you would have found (its reward) with Me."
