In the sound divine hadith (1) it is related that God will say on the Day of Resurrection: “My servant, I was sick and you did not visit Me.” He will reply, “Lord, how could I visit You when You are the Lord of all realms?” He will say, “Did you not know that My servant So-and-so was ill and you did not visit him?
