The word(s) "heir" appears 1616 time(s) in 1106 verse(s) in Quran in Mohsin Khan translation.

(911) But those who believe and do righteous good deeds, and believe in that which is sent down to Muhammad (صلى الله عليه وسلم) - for it is the truth from their Lord - He will expiate from them their sins, and will make good their state.

(912) That is because those who disbelieve follow falsehood, while those who believe follow the truth from their Lord. Thus does Allah set forth for mankind their parables.

(913) So, when you meet (in fight - Jihad in Allah's Cause) those who disbelieve, smite (their) necks till when you have killed and wounded many of them, then bind a bond firmly (on them, i.e. take them as captives). Thereafter (is the time) either for generosity (i.e. free them without ransom), or ransom (according to what benefits Islam), until the war lays down its burden. Thus [you are ordered by Allah to continue in carrying out Jihad against the disbelievers till they embrace Islam and are saved from the punishment in the Hell-fire or at least come under your protection], but if it had been Allah's Will, He Himself could certainly have punished them (without you). But (He lets you fight) in order to test some of you with others. But those who are killed in the Way of Allah, He will never let their deeds be lost.

(914) He will guide them and set right their state.

(915) And admit them to Paradise which He has made known to them (i.e. they will know their places in Paradise better than they used to know their homes in the world). [Tafsir Ibn Kathir ]

(916) But those who disbelieve (in the Oneness of Allah - Islamic Monotheism), for them is destruction, and (Allah) will make their deeds vain.

(917) That is because they hate that which Allah has sent down (this Qur'an and Islamic laws, etc.); so He has made their deeds fruitless.

(918) Certainly Allah will admit those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, to Gardens under which rivers flow (Paradise); while those who disbelieve enjoy themselves and eat as cattle eat; and the Fire will be their abode.

(919) Is he who is on a clear proof from his Lord, like those for whom their evil deeds that they do are beautified for them, while they follow their own lusts (evil desires)?

(920) The description of Paradise which the Muttaqun (the pious. See V.2:2) have been promised (is that) in it are rivers of water the taste and smell of which are not changed, rivers of milk of which the taste never changes, rivers of wine delicious to those who drink, and rivers of clarified honey (clear and pure) therein for them is every kind of fruit, and forgiveness from their Lord. (Are these) like those who shall dwell for ever in the Fire and be given to drink boiling water so that it cuts up their bowels?
