Kutoka kwa Abdullah bin Mas'ud (Radhi za Allah ziwe juu yake) reported: "I visited Mtume (Rehema na amani za Allah ziwe juu yake) when he was suffering fever. I said, "You seem to be suffering greatly, Ewe Mjumbe wa Allah." Mtume (Rehema na amani za Allah ziwe juu yake) replied, "Yes, I suffer as much as two persons." I said, "Is that because you have a double reward?" He replied that that was so and then said, "No Muislamu is afflicted by a harm, be it the pricking of a thorn or something more (painful than that), but Allah thereby causes his sins to fall away just as a tree sheds its leaves".."

Ibn Mas'ud (May Allah be pleased with him) reported: I visited the Prophet (ﷺ) when he was suffering fever. I said, "You seem to be suffering greatly, O Messenger of Allah." The Prophet (ﷺ) replied, "Yes, I suffer as much as two persons." I said, "Is that because you have a double reward?" He replied that that was so and then said, "No Muslim is afflicted by a harm, be it the pricking of a thorn or something more (painful than that), but Allah thereby causes his sins to fall away just as a tree sheds its leaves"..
