The word(s) "heirs" appears 42 time(s) in 40 verse(s) in Quran in Mohsin Khan translation.

(11) They will long to get out of the Fire, but never will they get out therefrom; and theirs will be a lasting torment.

(12) And so judge (you O Muhammad صلى الله عليه وسلم) among them by what Allah has revealed and follow not their vain desires, but beware of them lest they turn you (O Muhammad صلى الله عليه وسلم) far away from some of that which Allah has sent down to you. And if they turn away, then know that Allah's Will is to punish them for some sins of theirs. And truly, most of men are Fasiqun (rebellious and disobedient to Allah).

(13) Allah will say: "This is a Day on which the truthful will profit from their truth: theirs are Gardens under which rivers flow (in Paradise) - they shall abide therein forever. Allah is pleased with them and they with Him. That is the great success (Paradise).

(14) 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).

(15) 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.

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

(17) 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)

(18) 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.

(19) 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.

(20) 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.
