The word(s) "theirs" appears 87 time(s) in 78 verse(s) in Quran in Muhammad Pickthal translation.

(31) And of the wandering Arabs there is he who taketh that which he expendeth (for the cause of Allah) as a loss, and awaiteth (evil) turns of fortune for you (that he may be rid of it). The evil turn of fortune will be theirs. Allah is Hearer, Knower.

(32) Lo! Allah hath bought from the believers their lives and their wealth because the Garden will be theirs: they shall fight in the way of Allah and shall slay and be slain. It is a promise which is binding on Him in the Torah and the Gospel and the Qur'an. Who fulfilleth His covenant better than Allah? Rejoice then in your bargain that ye have made, for that is the supreme triumph.

(33) Unto Him is the return of all of you; it is a promise of Allah in truth. Lo! He produceth creation, then reproduceth it, that He may reward those who believe and do good works with equity; while, as for those who disbelieve, theirs will be a boiling drink and painful doom because they disbelieved.

(34) theirs are good tidings in the life of the world and in the Hereafter - There is no changing the Words of Allah - that is the Supreme Triumph.

(35) This world's portion (will be theirs), then unto Us is their return. Then We make them taste a dreadful doom because they used to disbelieve.

(36) Save those who persevere and do good works. theirs will be forgiveness and a great reward.

(37) Then, when they led him off, and were of one mind that they should place him in the depth of the pit, We inspired in him: Thou wilt tell them of this deed of theirs when they know (thee) not.

(38) Such as persevere in seeking their Lord's Countenance and are regular in prayer and spend of that which We bestow upon them secretly and openly, and overcome evil with good. theirs will be the sequel of the (heavenly) Home,

(39) And those who break the covenant of Allah after ratifying it, and sever that which Allah hath commanded should be joined, and make mischief in the earth: theirs is the curse and theirs the ill abode.

(40) And they assign unto Allah that which they (themselves) dislike, and their tongues expound the lie that the better portion will be theirs. Assuredly theirs will be the Fire, and they will be abandoned.
