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

(481) And We created not the heavens and the earth and all that is between them except with truth, and the Hour is surely coming, so overlook (O Muhammad صلى الله عليه و سلم) their faults with gracious forgiveness. [This was before the ordainment of Jihad - holy fighting in Allah's cause].

(482) Your Ilah (God) is One Ilah (God - Allah, none has the right to be worshipped but He). But for those who believe not in the Hereafter, their hearts deny (the faith in the Oneness of Allah), and they are proud.

(483) They may bear their own burdens in full on the Day of Resurrection, and also of the burdens of those whom they misled without knowledge. Evil indeed is that which they shall bear!

(484) Those before them indeed plotted, but Allah struck at the foundation of their building, and then the roof fell down upon them, from above them, and the torment overtook them from directions they did not perceive.

(485) Do they (the disbelievers and polytheists) await but that the angels should come to them [to take away their souls (at death)], or there should come the command (i.e. the torment or the Day of Resurrection) of your Lord? Thus did those before them. And Allah wronged them not, but they used to wrong themselves.

(486) Then, the evil results of their deeds overtook them, and that at which they used to mock at surrounded them.

(487) If you (O Muhammad صلى الله عليه و سلم) covet for their guidance, then verily Allah guides not those whom He makes to go astray (or none can guide him whom Allah sends astray). And they will have no helpers.

(488) And they swear by Allah their strongest oaths, that Allah will not raise up him who dies. Yes, (He will raise them up), - a promise (binding) upon Him in truth, but most of mankind know not.

(489) (They are) those who remained patient (in this world for Allah's sake), and put their trust in their Lord (Allah Alone).

(490) Or that He may catch them in the midst of their going to and fro (in their jobs), so that there be no escape for them (from Allah's punishment)?
