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

(191) And when they (who call themselves Christians) listen to what has been sent down to the Messenger (Muhammad صلى الله عليه وسلم), you see their eyes overflowing with tears because of the truth they have recognised. They say: "Our Lord! We believe; so write us down among the witnesses.

(192) Allah has made the Ka'bah, the Sacred House, an asylum of security and benefits (e.g.Hajj and 'Umrah) for mankind, and also the Sacred Month and the animals of offerings and the garlanded (people or animals marked with the garlands on their necks made from the outer part of the stem of the Makkah trees for their security), that you may know that Allah has knowledge of all that is in the heavens and all that is in the earth, and that Allah is the All-Knower of each and everything.

(193) And when it is said to them: "Come to what Allah has revealed and unto the Messenger (Muhammad صلى الله عليه وسلم for the verdict of that which you have made unlawful)." They say: "Enough for us is that which we found our fathers following," even though their fathers had no knowledge whatsoever nor guidance.

(194) O you who believe! When death approaches any of you, and you make a bequest, (then take) the testimony of two just men of your own folk or two others from outside, while you are travelling through the land and death befalls on you. Detain them both after As-Salat (the prayer), (then) if you are in doubt (about their truthfulness), let them both swear by Allah (saying): "We wish not for any worldly gain in this, even though he (the beneficiary) be our near relative. We shall not hide Testimony of Allah, for then indeed we should be of the sinful."

(195) If then it gets known that these two had been guilty of sin, let two others stand forth in their places, nearest in kin from among those who claim a lawful right. Let them swear by Allah (saying): "We affirm that our testimony is truer than that of both of them, and that we have not trespassed (the truth), for then indeed we should be of the wrong-doers."

(196) That should make it closer (to the fact) that their testimony would be in its true shape (and thus accepted), or else they would fear that (other) oaths would be admitted after their oaths. And fear Allah and listen (with obedience to Him). And Allah guides not the people who are Al-Fasiqun (the rebellious and disobedient).

(197) 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).

(198) All praises and thanks be to Allah, Who (Alone) created the heavens and the earth, and originated the darkness and the light; yet those who disbelieve hold others as equal with their Lord.

(199) And never an Ayah (sign) comes to them from the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord, but that they have been turning away from it.

(200) Have they not seen how many a generation before them We have destroyed whom We had established on the earth such as We have not established you? And We poured out on them rain from the sky in abundance, and made the rivers flow under them. Yet We destroyed them for their sins, and We created after them other generations.
