Narrated Abu Huraira (Radi-Allahu 'anhu):

I heard Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) saying, "The good
deeds of any person will not make him enter Paradise." (i.e., None can
enter Paradise through his good deeds.) They (the Prophet's companions)
said, 'Not even you, O Allah's Apostle?' He said, "Not even myself, unless
Allah bestows His favor and mercy on me." So be moderate in your religious
deeds and do the deeds that are within your ability: and none of you should
wish for death, for if he is a good doer, he may increase his good deeds,
and if he is an evil doer, he may repent to Allah."
