Hisn Al Muslim

(Ali Ibn Abee Talib t related that he heard the Messenger of Allah r say: ‘If a man calls on his sick Muslim brother, it is as if he walks reaping the fruits of Paradise until he sits, and when he sits he is showered in mercy, and if this was in the morning, seventy thousand angles send prayers upon him until the evening, and if this was in the evening, seventy thousand angles send prayers upon him until the morning.)
