Al-Adab Al-Mufrad #519

Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Allah says: 'I asked you for food and you did not feed Me. He (His slave) will say, 'Lord, how could I feed You when You did not ask me for food and You are the Lord of the universe?' He will say, 'Do you not know that My slave so-and-so asked you for food and you did not feed him? Do you not know that if you had fed him, you would have found that action with Me? Son of Adam, I asked you for water and you did not give Me water.' The slave will reply, 'O Lord, how could I give you water when You are the Lord of the universe?' He will say, 'My slave so-and-so asked you for water and you did not give him water. Do you not know that if you had given him water, you would have found that action with Me? Son of Adam, I was ill and you did not visit Me.' He will say, 'O Lord, how could I visit You when You are the Lord of the universe?' He will say, 'Do you not know that My slave so-and-so was ill. If you had visited him you would have found that action with Me (or you would have found Me with him)."
