The word(s) "slain" appears 2 time(s) in 2 verse(s) in Quran in Saheeh International translation.

(1) So, We said, "Strike the slain man with part of it." Thus does Allah bring the dead to life, and He shows you His signs that you might reason.

(2) Because of that, We decreed upon the Children of Israel that whoever kills a soul unless for a soul or for corruption [done] in the land - it is as if he had slain mankind entirely. And whoever saves one - it is as if he had saved mankind entirely. And our messengers had certainly come to them with clear proofs. Then indeed many of them, [even] after that, throughout the land, were transgressors.
