The word(s) "mates" appears 6 time(s) in 5 verse(s) in Quran in Mohsin Khan translation.

(1) And give glad tidings to those who believe and do righteous good deeds, that for them will be Gardens under which rivers flow (Paradise). Every time they will be provided with a fruit therefrom, they will say: "This is what we were provided with before," and they will be given things in resemblance (i.e. in the same form but different in taste) and they shall have therein Azwajun Mutahharatun (purified mates or wives) and they will abide therein forever.

(2) Say: "Shall I inform you of things far better than those? For Al-Muttaqun (the pious - See V.2:2) there are Gardens (Paradise) with their Lord, underneath which rivers flow. Therein (is their) eternal (home) and Azwajun Mutahharatun (purified mates or wives). And Allah will be pleased with them. And Allah is All-Seer of the (His) slaves".

(3) But those who believe (in the Oneness of Allah - Islamic Monotheism) and do deeds of righteousness, We shall admit them to Gardens under which rivers flow (Paradise), abiding therein forever. Therein they shall have Azwajun Mutahharatun (purified mates or wives), and We shall admit them to shades wide and ever deepening (Paradise) .

(4) And Allah has made for you Azwaj (mates or wives) of your own kind, and has made for you, from your wives, sons and grandsons, and has bestowed on you good provision. Do they then believe in false deities and deny the Favour of Allah (by not worshipping Allah Alone).

(5) The Creator of the heavens and the earth. He has made for you mates from yourselves, and for the cattle (also) mates. By this means He creates you (in the wombs). There is nothing like Him; and He is the All-Hearer, the All-Seer.
