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

(41) The fools among the people (pagans, hypocrites, and Jews) will say, "What has turned them (Muslims) from their Qiblah [prayer direction (towards Jerusalem)] to which they used to face in prayer." Say, (O Muhammad صلى الله عليه وسلم) "To Allah belong both, east and the west. He guides whom He wills to the Straight Way."

(42) Thus We have made you [true Muslims - real believers of Islamic Monotheism, true followers of Prophet Muhammad صلى الله عليه وسلم and his Sunnah (legal ways)], a just (and the best) nation, that you be witnesses over mankind and the Messenger (Muhammad صلى الله عليه وسلم) be a witness over you. And We made the Qiblah (prayer direction towards Jerusalem) which you used to face, only to test those who followed the Messenger (Muhammad صلى الله عليه وسلم) from those who would turn on their heels (i.e. disobey the Messenger). Indeed it was great (heavy) except for those whom Allah guided. And Allah would never make your faith (prayers) to be lost (i.e. your prayers offered towards Jerusalem). Truly, Allah is full of Kindness, the Most Merciful towards mankind.

(43) Verily! We have seen the turning of your (Muhammad's صلى الله عليه وسلم) face towards the heaven. Surely, We shall turn you to a Qiblah (prayer direction) that shall please you, so turn your face in the direction of Al-Masjid-al-Haram (at Makkah). And wheresoever you people are, turn your faces (in prayer) in that direction. Certainly, the people who were given the Scripture (i.e. Jews and the Christians) know well that, that (your turning towards the direction of the Ka'bah at Makkah in prayers) is the truth from their Lord. And Allah is not unaware of what they do.

(44) And even if you were to bring to the people of the Scripture (Jews and Christians) all the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they would not follow your Qiblah (prayer direction), nor are you going to follow their Qiblah (prayer direction). And they will not follow each other's Qiblah (prayer direction). Verily, if you follow their desires after that which you have received of knowledge (from Allah), then indeed you will be one of the Zalimun (polytheists, wrong-doers).

(45) Those to whom We gave the Scripture (Jews and Christians) recognise him (Muhammad صلى الله عليه وسلم or the Ka'bah at Makkah) as they recognise their sons. But verily, a party of them conceal the truth while they know it - [i.e. the qualities of Muhammad صلى الله عليه وسلم which are written in the Taurat (Torah) and the Injeel (Gospel)].

(46) For every nation there is a direction to which they face (in their prayers). So hasten towards all that is good. Wheresoever you may be, Allah will bring you together (on the Day of Resurrection). Truly, Allah is Able to do all things.

(47) They are those on whom are the Salawat (i.e. who are blessed and will be forgiven) from their Lord, and (they are those who) receive His Mercy, and it is they who are the guided ones.

(48) Except those who repent and do righteous deeds, and openly declare (the truth which they concealed). These, I will accept their repentance. And I am the One Who accepts repentance, the Most Merciful.

(49) They will abide therein (under the curse in Hell), their punishment will neither be lightened, nor will they be reprieved.

(50) When those who were followed, disown (declare themselves innocent of) those who followed (them), and they see the torment, then all their relations will be cut off from them.
