Mishkat al-Masabih 1586

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 [good deeds].” Razln transmitted it.
