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

(521) (And remember) the Day when We shall call together call human beings with their (respective) Imam [their Prophets, or their records of good and bad deeds, or their Holy Books like the Qur'an, the Taurat (Torah), the Injeel (Gospel), the leaders whom the people followed in this world.]. So whosoever is given his record in his right hand, such will read their records, and they will not be dealt with unjustly in the least.

(522) "Or you have a garden of date-palms and grapes, and cause rivers to gush forth in their midst abundantly;

(523) And he whom Allah guides, he is led aright; but he whom He sends astray, for such you will find no Auliya' (helpers and protectors), besides Him, and We shall gather them together on the Day of Resurrection on their faces, blind, dumb and deaf; their abode will be Hell; whenever it abates, We shall increase for them the fierceness of the Fire.

(524) That is their recompense, because they denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and said: "When we are bones and fragments, shall we really be raised up as a new creation?"

(525) Say (O Muhammad صلى الله عليه و سلم to them): "Believe in it (the Qur'an) or do not believe (in it). Verily those who were given knowledge before it (the Jews and the Christians like 'Abdullah bin Salam and Salman Al-Farisi), when it is recited to them, fall down on their faces in humble prostration."

(526) And they fall down on their faces weeping and it increases their humility.

(527) No knowledge have they of such a thing, nor had their fathers. Mighty is the word that comes out of their mouths [i.e. He begot sons and daughters]. They utter nothing but a lie .

(528) Perhaps, you, would kill yourself (O Muhammad صلى الله عليه وسلم) in grief, over their footsteps (for their turning away from you), because they believe not in this narration (the Qur'an).

(529) (Remember) when the young men fled for refuge (from their disbelieving folk) to the Cave. They said: "Our Lord! Bestow on us mercy from Yourself, and facilitate for us our affair in the right way!"

(530) Therefore We covered up their (sense of) hearing (causing them to go in deep sleep) in the Cave for a number of years.
