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

(1) If a wound should touch you - there has already touched the [opposing] people a wound similar to it. And these days [of varying conditions] We alternate among the people so that Allah may make evident those who believe and [may] take to Himself from among you martyrs - and Allah does not like the wrongdoers -

(2) And [the believers among] those to whom We have given the [previous] Scripture rejoice at what has been revealed to you, [O Muhammad], but among the [opposing] factions are those who deny part of it. Say, "I have only been commanded to worship Allah and not associate [anything] with Him. To Him I invite, and to Him is my return."
