The word(s) "cooperate" appears 3 time(s) in 2 verse(s) in Quran in Saheeh International translation.

(1) O you who have believed, do not violate the rites of Allah or [the sanctity of] the sacred month or [neglect the marking of] the sacrificial animals and garlanding [them] or [violate the safety of] those coming to the Sacred House seeking bounty from their Lord and [His] approval. But when you come out of ihram, then [you may] hunt. And do not let the hatred of a people for having obstructed you from al-Masjid al-Haram lead you to transgress. And cooperate in righteousness and piety, but do not cooperate in sin and aggression. And fear Allah; indeed, Allah is severe in penalty.

(2) If you two [wives] repent to Allah, [it is best], for your hearts have deviated. But if you cooperate against him - then indeed Allah is his protector, and Gabriel and the righteous of the believers and the angels, moreover, are [his] assistants.
