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

(541) And keep yourself (O Muhammad صلى الله عليه وسلم) patiently with those who call on their Lord (i.e. your companions who remember their Lord with glorification, praising in prayers, and other righteous deeds) morning and afternoon, seeking His Face; and let not your eyes overlook them, desiring the pomp and glitter of the life of the world; and obey not him whose heart We have made heedless of Our Remembrance, and who follows his own lusts, and whose affair (deeds) has been lost.

(542) And say: "The truth is from your Lord." Then whosoever wills, let him believe; and whosoever wills, let him disbelieve. Verily, We have prepared for the Zalimun (polytheists and wrong-doers.), a Fire whose walls will be surrounding them (disbelievers in the Oneness of Allah). And if they ask for help (relief, water), they will be granted water like boiling oil, that will scald their faces. Terrible is the drink, and an evil Murtafaq (dwelling, resting place.)!

(543) I (Allah) made them (Iblis and his offspring) not to witness (nor took their help in) the creation of the heavens and the earth and not (even) their own creation, nor was I (Allah) to take the misleaders as helpers.

(544) And nothing prevents men from believing, (now) when the guidance (the Qur'an) has come to them, and from asking Forgiveness of their Lord, except that the ways of the ancients be repeated with them (i.e. their destruction decreed by Allah), or the torment be brought to them face to face?

(545) And who does more wrong than he who is reminded of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord, but turns away from them, forgetting what (deeds) his hands have sent forth. Truly, We have set veils over their hearts lest they should understand this (the Qur'an), and in their ears, deafness. And if you (O Muhammad صلى الله عليه وسلم) call them to guidance, even then they will never be guided.

(546) And your Lord is Most Forgiving, Owner of Mercy. Were He to call them to account for what they have earned, then surely, He would have hastened their punishment. But they have their appointed time, beyond which they will find no escape.

(547) And these towns (population, - 'Ad, Thamud) We destroyed them when they did wrong. And We appointed a fixed time for their destruction.

(548) But when they reached the junction of the two seas, they forgot their fish, and it took its way through the sea as in a tunnel.

(549) [Musa (Moses)] said: "That is what we have been seeking." So they went back retracing their footsteps.

(550) "So we intended that their Lord should change him for them for one better in righteousness and nearer to mercy.
