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

(231) And they swear their strongest oaths by Allah, that if there came to them a sign, they would surely believe therein. Say: "Signs are but with Allah and what will make you (Muslims) perceive that (even) if it (the sign) came, they will not believe?"

(232) And We shall turn their hearts and their eyes away (from guidance), as they refused to believe therein for the first time, and We shall leave them in their trespass to wander blindly.

(233) And even if We had sent down unto them angels, and the dead had spoken unto them, and We had gathered together all things before their very eyes, they would not have believed, unless Allah willed, but most of them behave ignorantly.

(234) And so We have appointed for every Prophet enemies - Shayatin (devils) among mankind and jinn, inspiring one another with adorned speech as a delusion (or by way of deception). If your Lord had so willed, they would not have done it; so leave them alone with their fabrications. (Tafsir Qurtubi)

(235) And why should you not eat of that (meat) on which Allah's Name has been pronounced (at the time of slaughtering the animal), while He has explained to you in detail what is forbidden to you, except under compulsion of necessity? And surely many do lead (mankind) astray by their own desires through lack of knowledge. Certainly your Lord knows best the transgressors.

(236) Eat not (O believers) of that (meat) on which Allah's Name has not been pronounced (at the time of the slaughtering of the animal), for sure it is Fisq (a sin and disobedience of Allah). And certainly, the Shayatin (devils) do inspire their friends (from mankind) to dispute with you, and if you obey them [by making Al-Maitah (a dead animal) legal by eating it], then you would indeed be Mushrikun (polytheists); [because they (devils and their friends) made lawful to you to eat that which Allah has made unlawful to eat and you obeyed them by considering it lawful to eat, and by doing so you worshipped them; and to worship others besides Allah is polytheism].

(237) And thus We have set up in every town great ones of its wicked people to plot therein. But they plot not except against their ownselves, and they perceive (it) not.

(238) For them will be the home of peace (Paradise) with their Lord. And He will be their Wali (Helper and Protector) because of what they used to do.

(239) And on the Day when He will gather them (all) together (and say): "O you assembly of jinn! Many did you mislead of men," and their Auliya' (friends and helpers) amongst men will say: "Our Lord! We benefited one from the other, but now we have reached our appointed term which You did appoint for us." He will say: "The Fire be your dwelling-place, you will dwell therein forever, except as Allah may will. Certainly your Lord is All-Wise, All-Knowing."

(240) This is because your Lord would not destroy the (populations of) towns for their wrong-doing (i.e. associating others in worship along with Allah) while their people were unaware (so the Messengers were sent).
