Volume # 7 Hadith # 571
Narrator: Ibn Masud (RA)
I visited the Prophet (SAW) while he was having a high fever. I touched him and said, "You have a very high fever" He said, "Yes, as
much fever as two of you may have." I said, "You will have a double reward?" He said, "Yes No Muslim is afflicted with hurt caused by disease or some other inconvenience, but that Allah will remove his sins as a tree sheds its leaves."
