The word(s) "diminution" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) Whosoever desires the life of the world and its glitter, to them We shall pay in full (the wages of) their deeds therein, and they will have no diminution therein.

(2) So be not in doubt (O Muhammad صلى الله عليه و سلم) as to what these people (pagans and polytheists) worship. They worship nothing but what their fathers worshipped before (them). And verily, We shall repay them in full their portion without diminution.
