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

(61) And divorced women shall wait (as regards their marriage) for three menstrual periods, and it is not lawful for them to conceal what Allah has created in their wombs, if they believe in Allah and the Last Day. And their husbands have the better right to take them back in that period, if they wish for reconciliation. And they (women) have rights (over their husbands as regards living expenses) similar (to those of their husbands) over them (as regards obedience and respect) to what is reasonable, but men have a degree (of responsibility) over them. And Allah is All-Mighty, All-Wise.

(62) And when you have divorced women and they have fulfilled the term of their prescribed period, either take them back on reasonable basis or set them free on reasonable basis. But do not take them back to hurt them, and whoever does that, then he has wronged himself. And treat not the Verses (Laws) of Allah as a jest, but remember Allah's Favours on you (i.e. Islam), and that which He has sent down to you of the Book (i.e. the Qur'an) and Al-Hikmah (the Prophet's Sunnah - legal ways - Islamic jurisprudence.) whereby He instructs you. And fear Allah, and know that Allah is All-Aware of everything.

(63) And when you have divorced women and they have fulfilled the term of their prescribed period, do not prevent them from marrying their (former) husbands, if they mutually agree on reasonable basis. This (instruction) is an admonition for him among you who believes in Allah and the Last Day. That is more virtuous and purer for you. Allah knows and you know not.

(64) The mothers shall give suck to their children for two whole years, (that is) for those (parents) who desire to complete the term of suckling, but the father of the child shall bear the cost of the mother's food and clothing on a reasonable basis. No person shall have a burden laid on him greater than he can bear. No mother shall be treated unfairly on account of her child, nor father on account of his child. And on the (father's) heir is incumbent the like of that (which was incumbent on the father). If they both decide on weaning, by mutual consent, and after due consultation, there is no sin on them. And if you decide on a foster suckling-mother for your children, there is no sin on you, provided you pay (the mother) what you agreed (to give her) on reasonable basis. And fear Allah and know that Allah is All-Seer of what you do.

(65) And those of you who die and leave wives behind them, they (the wives) shall wait (as regards their marriage) for four months and ten days, then when they have fulfilled their term, there is no sin on you if they (the wives) dispose of themselves in a just and honourable manner (i.e. they can marry). And Allah is Well-Acquainted with what you do.

(66) There is no sin on you, if you divorce women while yet you have not touched (had sexual relation with) them, nor appointed unto them their Mahr (bridal-money given by the husband to his wife at the time of marriage). But bestow on them (a suitable gift), the rich according to his means, and the poor according to his means, a gift of reasonable amount is a duty on the doers of good.

(67) And those of you who die and leave behind wives should bequeath for their wives a year's maintenance and residence without turning them out, but if they (wives) leave, there is no sin on you for that which they do of themselves, provided it is honourable (e.g. lawful marriage). And Allah is All-Mighty, All-Wise .

(68) Did you (O Muhammad صلى الله عليه وسلم) not think of those who went forth from their homes in thousands, fearing death? Allah said to them, "Die". And then He restored them to life. Truly, Allah is full of bounty to mankind, but most men thank not.

(69) Have you not thought about the group of the Children of Israel after (the time of) Musa (Moses)? When they said to a Prophet of theirs, "Appoint for us a king and we will fight in Allah's Way." He said, "Would you then refrain from fighting, if fighting was prescribed for you?" They said, "Why should we not fight in Allah's Way while we have been driven out of our homes and our children (families have been taken as captives)?" But when fighting was ordered for them, they turned away, all except a few of them. And Allah is All-Aware of the Zalimun (polytheists and wrong-doers).

(70) And their Prophet (Samuel عليه السلام) said to them, "Indeed Allah has appointed Talut (Saul) as a king over you." They said, "How can he be a king over us when we are fitter than him for the kingdom, and he has not been given enough wealth." He said: "Verily, Allah has chosen him above you and has increased him abundantly in knowledge and stature. And Allah grants His kingdom to whom He wills. And Allah is All-Sufficient for His creatures' needs, All-Knower."
