The word(s) "heirs" appears 91 time(s) in 81 verse(s) in Quran in Muhammad Pickthal translation.

(41) And those who break the covenant of Allah after ratifying it, and sever that which Allah hath commanded should be joined, and make mischief in the earth: theirs is the curse and theirs the ill abode.

(42) And they assign unto Allah that which they (themselves) dislike, and their tongues expound the lie that the better portion will be theirs. Assuredly theirs will be the Fire, and they will be abandoned.

(43) By Allah, We verily sent messengers unto the nations before thee, but the devil made their deeds fairseeming unto them. So he is their patron this day, and theirs will be a painful doom.

(44) And when those who ascribed partners to Allah behold those partners of theirs, they will say: Our Lord! these are our partners unto whom we used to cry instead of Thee. But they will fling to them the saying: Lo! ye verily are liars!

(45) Lo! those who disbelieve the revelations of Allah, Allah guideth them not and theirs will be a painful doom.

(46) Whoso disbelieveth in Allah after his belief - save him who is forced thereto and whose heart is still content with the Faith - but whoso findeth ease in disbelief: On them is wrath from Allah. Theirs will be an awful doom.

(47) A brief enjoyment (will be theirs); and theirs a painful doom.

(48) Lo! this Qur'an guideth unto that which is straightest, and giveth tidings unto the believers who do good works that theirs will be a great reward.

(49) (But hath made it) straight, to give warning of stern punishment from Him, and to bring unto the believers who do good works the news that theirs will be a fair reward,

(50) As for such, theirs will be Gardens of Eden, wherein rivers flow beneath them; therein they will be given armlets of gold and will wear green robes of finest silk and gold embroidery, reclining upon throne therein. Blest the reward, and fair the resting-place!
