Shaqiq said he visited ‘Abdallah b. Mas'ud when he was ill, and he began to weep. On being reproved by someone he said, "I am not weeping because of the illness, because I heard God’s messenger say that illness is an atonement; I am weeping simply because it has come to me when my powers are weakened and did not come when I was active, because a servant of God has recorded for him such reward when he is ill as was being recorded for him before he became ill and the illness prevented him from doing .”
‘Umar b. al-Khattab reported God’s messenger as saying, “When you visit an invalid tell him to make supplication for you, for his supplication is like that of the angels.”
Anas reported God’s messenger as stating that the Lord who is glorious and exalted says, "By my might and glory, I will not take out of the world anyone I intend to forgive till I get payment for every sin which hangs on his neck by illness in his body and scarcity in his provision.”
