The word(s) "adds" appears 3 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Praise be to Allah, Who created (out of nothing) the heavens and the earth, Who made the angels, messengers with wings,- two, or three, or four (pairs): He adds to Creation as He pleases: for Allah has power over all things.

(2) He it is That has made you inheritors in the earth: if, then, any do reject (Allah), their rejection (works) against themselves: their rejection but adds to the odium for the Unbelievers in the sight of their Lord: their rejection but adds to (their own) undoing.
