Narrated
Al-Mughîrah: The Prophet صلى الله عليه وسلم used to offer night prayers till his feet
became swollen. Somebody said to him, “Allah has forgiven you your sins of the
past and the future.” On that, He said, “Shouldn’t I be thankful slave of
Allah?”
(Sahîh Al-Bukhârî, Vol. 6, Hadîth No. 360).
