The word(s) "abatement" appears 2 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Be not then in doubt as to what these men worship. They worship nothing but what their fathers worshipped before (them): but verily We shall pay them back (in full) their portion without (the least) abatement.

(2) It is he whom Allah guides, that is on true Guidance; but he whom He leaves astray - for such wilt thou find no protector besides Him. On the Day of Judgment We shall gather, them together, prone on their faces, blind, dumb, and deaf: their abode will be Hell: every time it shows abatement, We shall increase from them the fierceness of the Fire.
