Verily Allah does not wrong a Believer for any good deed

Rasoolullah (Sallallahu alaihi wa sallam) said:

“Verily Allah does not wrong a Believer for any good deed. In this world he will prosper by virtue of it and in the Aakhirat he will be rewarded for it. The kaafir on the other hand is fed by virtue of the good acts he does for God in this world until he reaches the Aakhirat where he will not have any good to be rewarded for.” (Mishkaat)

Comment: The gist of the Hadeeth is that the Mu’min is showered with Allah Ta’ala’s grace, whilst the kaafir will be treated equitably. (Mirqaat)
