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

(321) Except those of the Mushrikun (see V.2:105) with whom you have a treaty, and who have not subsequently failed you in aught, nor have supported anyone against you. So fulfil their treaty to them for the end of their term. Surely Allah loves Al-Mattaqun (the pious - See V.2:2).

(322) Then when the Sacred Months (the 1st, 7th, 11th, and 12th months of the Islamic calendar) have passed, then kill the Mushrikun (See V.2:105) wherever you find them, and capture them and besiege them, and lie in wait for them in each and every ambush. But if they repent and perform As-Salat (Iqamat-as-Salat), and give Zakat, then leave their way free. Verily, Allah is Oft-Forgiving, Most Merciful.

(323) How (can there be such a covenant with them) that when you are overpowered by them, they regard not the ties, either of kinship or of covenant with you? With (good words from) their mouths they please you, but their hearts are averse to you, and most of them are Fasiqun (rebellious, disobedient to Allah).

(324) But if they violate their oaths after their covenant, and attack your religion with disapproval and criticism, then fight (you) the leaders of disbelief (chiefs of Quraish pagans of Makkah) - for surely their oaths are nothing to them - so that they may stop (evil actions).

(325) Will you not fight a people who have violated their oaths (pagans of Makkah), and intended to expel the Messenger while they did attack you first? Do you fear them? Allah has more right that you should fear Him if you are believers.

(326) And remove the anger of their (believers') hearts. Allah accepts the repentance of whom He wills. Allah is All-Knowing, All-Wise.

(327) Do you think that you shall be left alone while Allah has not yet tested those among you who have striven hard and fought and have not taken Walijah [(Bitanah - helpers, advisors and consultants from disbelievers, pagans.) giving openly to them their secrets] besides Allah, and His Messenger, and the believers. Allah is Well-Acquainted with what you do.

(328) It is not for the Mushrikun (polytheists, idolaters, pagans, disbelievers in the Oneness of Allah), to maintain the Mosques of Allah (i.e. to pray and worship Allah therein, to look after their cleanliness and their building,), while they witness against their ownselves of disbelief. The works of such are in vain and in Fire shall they abide.

(329) Those who believed (in the Oneness of Allah - Islamic Monotheism) and emigrated and strove hard and fought in Allah's Cause with their wealth and their lives are far higher in degree with Allah. They are the successful.

(330) Their Lord gives them glad tidings of Mercy from Him, and His being pleased (with them), and of Gardens (Paradise) for them wherein are everlasting delights.
