The word(s) "heir" appears 1348 time(s) in 978 verse(s) in Quran in Muhammad Pickthal translation.

(671) Who forsake their beds to cry unto their Lord in fear and hope, and spend of that We have bestowed on them.

(672) And as for those who do evil, their retreat is the Fire. Whenever they desire to issue forth from thence, they are brought back thither. Unto them it is said: Taste the torment of the Fire which ye used to deny.

(673) Have they not seen how We lead the water to the barren land and therewith bring forth crops whereof their cattle eat, and they themselves? Will they not then see?

(674) Proclaim their real parentage. That will be more equitable in the sight of Allah. And if ye know not their fathers, then (they are) your brethren in the faith, and your clients. And there is no sin for you in the mistakes that ye make unintentionally, but what your hearts purpose (that will be a sin for you). Allah is ever Forgiving, Merciful.

(675) The Prophet is closer to the believers than their selves, and his wives are (as) their mothers. And the owners of kinship are closer one to another in the ordinance of Allah than (other) believers and the fugitives (who fled from Mecca), except that ye should do kindness to your friends. This is written in the Book (of nature).

(676) That He may ask the loyal of their loyalty. And He hath prepared a painful doom for the unfaithful.

(677) And verily they had already sworn unto Allah that they would not turn their backs (to the foe). An oath to Allah must be answered for.

(678) Allah already knoweth those of you who hinder, and those who say unto their brethren: "Come ye hither unto us!" and they come not to the stress of battle save a little,

(679) Being sparing of their help to you (believers). But when the fear cometh, then thou (Muhammad) seest them regarding thee with rolling eyes like one who fainteth unto death. Then, when the fear departeth, they scald you with sharp tongues in their greed for wealth (from the spoil). Such have not believed. Therefor Allah maketh their deeds fruitless. And that is easy for Allah.

(680) And when the true believers saw the clans, they said: This is that which Allah and His messenger promised us. Allah and His messenger are true. It did but confirm them in their faith and resignation.
