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

(511) A passing brief enjoyment (will be theirs), but they will have a painful torment.

(512) Truly, Allah is with those who fear Him (keep their duty unto Him), and those who are Muhsinun (good-doers. See the footenote of V.9:120).

(513) (And We said): "If you do good, you do good for your ownselves, and if you do evil (you do it) against yourselves." Then, when the second promise came to pass, (We permitted your enemies) to disgrace your faces and to enter the mosque (of Jerusalem) as they had entered it before, and to destroy with utter destruction all that fell in their hands.

(514) And if you (O Muhammad صلى الله عليه و سلم) turn away from them (kindred, poor, wayfarer whom We have ordered you to give their rights, but if you have no money at the time they ask you for it) and you are awaiting a mercy from your Lord for which you hope, then, speak unto them a soft kind word (i.e. Allah will give me and I shall give you).

(515) And do not kill anyone whose killing Allah has forbidden, except for a just cause. And whoever is killed wrongfully (Mazluman intentionally with hostility and oppression and not by mistake), We have given his heir the authority [to demand Qisas, - Law of Equality in punishment - or to forgive, or to take Diyah (blood money)]. But let him not exceed limits in the matter of taking life (i.e he should not kill except the killer). Verily, he is helped (by the Islamic law).

(516) The seven heavens and the earth and all that is therein, glorify Him and there is not a thing but glorifies His Praise. But you understand not their glorification. Truly, He is Ever Forbearing, Oft-Forgiving.

(517) And when you (Muhammad صلى الله عليه و سلم) recite the Qur'an, We put between you and those who believe not in the Hereafter, an invisible veil (or screen their hearts, so they hear or understand it not).

(518) And We have put coverings over their hearts lest they should understand it (the Qur'an), and in their ears deafness. And when you make mention of your Lord Alone [La ilaha illallah (none has the right to be worshipped but Allah) Islamic Monotheism (توحيد الله)] in the Qur'an, they turn on their backs, fleeing in extreme dislike.

(519) "Or some created thing that is yet greater (or harder) in your breasts (thoughts to be resurrected, even then you shall be resurrected)." Then, they will say: "Who shall bring us back (to life)?" Say: "He Who created you first!" Then, they will shake their heads at you and say: "When will that be?" Say: "Perhaps it is near!"

(520) Those whom they call upon [like 'Îsa (Jesus) - son of Maryam (Mary), 'Uzair (Ezra), angel] desire (for themselves) means of access to their Lord (Allah), as to which of them should be the nearest; and they ['Îsa (Jesus), 'Uzair (Ezra), angels and others] hope for His Mercy and fear His Torment. Verily, the Torment of your Lord is (something) to be afraid of!
