“When I was sick, you did not visit Me.”

{when I was ill}:

  Prophet Muhammad said: The God will say on The Day of Judgment, ‘Son of Adam, I was sick but you did not visit Me.’

    ‘My Lord, How could I visit You when You are The Lord of the worlds (all that exist)?’

    ‘Did you not know that one of My Servants was sick and you didn’t visit him? If you had visited him you would have found Me there.’

    Then The God will say, ‘Son of Adam, I needed food but you did not feed Me.’

    ‘My Lord, How could I feed You when You are the Lord of the worlds?’

    ‘Did you not know that one of My Servants was hungry but you did not feed him? If you had fed him you would have found its reward with Me.’

    ‘Son of Adam, I was thirsty, but you did not give Me something to drink.’

    ‘My Lord, How could I give a drink when You are The Lord of the worlds?’

    ‘Did you not know that one of My servants was thirsty but you did not give him a drink? If you had given him a drink, you would have found its reward with Me.’
