Mukhtasar Muslim

Sayyiduna Thawban (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he said: Whoever visits a sick person (by going to his place) is in a garden of Paradise until he returns.

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