I went in to visit the Prophet when he was jaded by fever, and touching him with my hand, I said, “You are seriously jaded by fever, messenger of God.” The Prophet replied, “Yes, I am twice as jaded as any of you.” I said, “That is because you have a double reward.” He replied that that was so and then said, “No Muslim is afflicted by injury, be it illness or something else, without God thereby causing his sins to drop away just as a tree sheds its leaves.”
She said, “The Prophet died lying between my breast and my collarbone. I will never feel bad about anyone having a painful death after what I saw the Prophet suffer.”
He and Abu Sa'id reported the Prophet as saying, “No Muslim is afflicted by difficulty, continuous pain, anxiety, grief, injury, or care, or even by a thorn with which he is pierced, without God thereby making an atonement for his sins.”
