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

(831) And Allah will deliver those who are the Muttaqun (the pious - See V.2:2) to their places of success (Paradise). Evil shall touch them not, nor shall they grieve.

(832) And those who kept their duty to their Lord (Al-Muttaqun ) will be led to Paradise in groups, till, when they reach it, and its gates will be opened (before their arrival for their reception) and its keepers will say: Salamun 'Alaikum (peace be upon you)! You have done well, so enter here to abide therein."

(833) And you will see the angels surrounding the Throne (of Allah) from all round, glorifying the praises of their Lord (Allah). And they (all the creatures) will be judged with truth. And it will be said, "All the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinn and all that exists)."

(834) Ha-Mim. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings].

(835) None disputes in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah but those who disbelieve. So let not their ability of going about here and there through the land (for their purposes) deceive you [O Muhammad صلى الله عليه وسلم, for their ultimate end will be the Fire of Hell]!

(836) The people of Nuh (Noah) and the Confederates after them denied (their Messengers) before these; and every (disbelieving) nation plotted against their Messenger to seize him, and disputed by means of falsehood to refute therewith the truth. So I seized them (with punishment), and how (terrible) was My punishment!

(837) Those (angels) who bear the Throne (of Allah) and those around it glorify the praises of their Lord, and believe in Him, and ask forgiveness for those who believe (in the Oneness of Allah) (saying): "Our Lord! You comprehend all things in mercy and knowledge, so forgive those who repent and follow Your Way, and save them from the torment of the blazing Fire!

(838) "Our Lord! And make them enter the 'Adn (Eden) Paradise (everlasting Gardens) which you have promised them - and to the righteous among their fathers, their wives, and their offspring! Verily, You are the All-Mighty, the All-Wise.

(839) And warn them (O Muhammad صلى الله عليه وسلم) of the Day that is drawing near (i.e. the Day of Resurrection), when the hearts will be choking the throats, and they can neither return them (hearts) to their chests nor can they throw them out. There will be no friend, nor an intercessor for the Zalimun (polytheists and wrong-doers), who could be given heed to.

(840) Have they not travelled in the land and seen what was the end of those who were before them? They were superior to them in strength, and in the traces (which they left) in the land. But Allah seized them with punishment for their sins. And none had they to protect them from Allah.
