The word(s) "theirs" appears 39 time(s) in 37 verse(s) in Quran in Mohsin Khan translation.

(11) theirs will be a bed of Hell (Fire), and over them coverings (of Hell-fire). Thus do We recompense the Zalimun (polytheists and wrong-doers).

(12) Verily, Allah has purchased of the believers their lives and their properties for (the price) that theirs shall be the Paradise. They fight in Allah's Cause, so they kill (others) and are killed. It is a promise in truth which is binding on Him in the Taurat (Torah) and the Injeel (Gospel) and the Qur'an. And who is truer to his covenant than Allah? Then rejoice in the bargain which you have concluded. That is the supreme success.

(13) Except those who show patience and do righteous good deeds: those, theirs will be forgiveness and a great reward (Paradise).

(14) They assign to Allah that which they dislike (for themselves), and their tongues assert the falsehood that the better things will be theirs. No doubt for them is the Fire, and they will be the first to be hastened on into it, and left there neglected. (Tafsir Al-Qurtubi)

(15) By Allah, We indeed sent (Messengers) to the nations before you (O Muhammad صلى الله عليه و سلم), but Shaitan (Satan) made their deeds fair-seeming to them. So he (Satan) is their Wali (helper) today (i.e. in this world), and theirs will be a painful torment.

(16) Verily! Those who believe not in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, Allah will not guide them and theirs will be a painful torment.

(17) Whoever disbelieved in Allah after his belief, except him who is forced thereto and whose heart is at rest with Faith; but such as open their breasts to disbelief, on them is wrath from Allah, and theirs will be a great torment.

(18) A passing brief enjoyment (will be theirs), but they will have a painful torment.

(19) And that cry of theirs ceased not, till We made them as a field that is reaped, extinct (dead).

(20) The true believers are only those, who believe in (the Oneness of) Allah and His Messenger (Muhammad صلى الله عليه وسلم): and when they are with him on some common matter, they go not away until they have asked his permission. Verily those who ask your permission, those are they who (really) believe in Allah and His Messenger. So if they ask your permission for some affairs of theirs, give permission to whom you will of them, and ask Allah for their forgiveness. Truly, Allah is Oft-Forgiving, Most Merciful.
