The word(s) "pair" appears 37 time(s) in 34 verse(s) in Quran in Muhammad Pickthal translation.

(21) And other (torment) of the kind in pairs (the two extremes)!

(22) Allah hath (now) revealed the fairest of statements, a Scripture consistent, (wherein promises of reward are) paired (with threats of punishment), whereat doth creep the flesh of those who fear their Lord, so that their flesh and their hearts soften to Allah's reminder. Such is Allah's guidance, wherewith He guideth whom He will. And him whom Allah sendeth astray, for him there is no guide.

(23) Say: O My slaves who have been prodigal to their own hurt! Despair not of the mercy of Allah, Who forgiveth all sins. Lo! He is the Forgiving, the Merciful.

(24) The Creator of the heavens and the earth. He hath made for you pairs of yourselves, and of the cattle also pairs, whereby He multiplieth you. Naught is as His likeness; and He is the Hearer, the Seer.

(25) And He it is Who sendeth down the saving rain after they have despaired, and spreadeth out His mercy. He is the Protecting Friend, the Praiseworthy.

(26) He Who created all the pairs, and appointed for you ships and cattle whereupon ye ride.

(27) It is not relaxed for them, and they despair therein.

(28) And all things We have created by pairs, that haply ye may reflect.

(29) Wherein is every kind of fruit in pairs.

(30) O ye who believe! Be not friendly with a folk with whom Allah is wroth, (a folk) who have despaired of the Hereafter as the disbelievers despair of those who are in the graves.
