'Allah Almighty will say on the Day of Resurrection, ?O son of Adam, I became sick and you did not visit Me!' and he will ask, ?O Lord, how can I visit You when You are the Lord of the worlds?' He Almighty will say, 'Did you not know that My servant so and so became sick and you did not visit him?! Did you not know that if you had visited him you would have found Me there with him [visiting a sick person is as visiting Allah]?!'
