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

(441) So when he had furnished them forth with their provisions, he put the (golden) bowl in his brother's bag. Then a crier cried: "O you (in) the caravan! Surely, you are thieves!"

(442) So he [Yusuf (Joseph)] began (the search) in their bags before the bag of his brother. Then he brought it out of his brother's bag. Thus did We plan for Yusuf (Joseph). He could not take his brother by the law of the king (as a slave), except that Allah willed it. (So Allah made the brothers to bind themselves with their way of "punishment, i.e. enslaving of a thief.") We raise to degrees whom We will, but over all those endowed with knowledge is the All-Knowing (Allah).

(443) And when the caravan departed, their father said: "I do indeed feel the smell of Yusuf (Joseph), if only you think me not a dotard (a person who has weakness of mind because of old age)."

(444) That is of the news of the Ghaib (Unseen) which We reveal to you (O Muhammad صلى الله عليه و سلم). You were not (present) with them when they arranged their plan together, and (while) they were plotting.

(445) (They were reprieved) until, when the Messengers gave up hope and thought that they were denied (by their people), then came to them Our Help, and whomsoever We willed were rescued. And Our punishment cannot be warded off from the people who are Mujrimun (criminals, sinners, disbelievers, polytheists).

(446) Indeed in their stories, there is a lesson for men of understanding. It (the Qur'an) is not a forged statement but a confirmation of (Allah's existing Books) which were before it [i.e. the Taurat (Torah), the Injeel (Gospel) and other Scriptures of Allah] and a detailed explanation of everything and a guide and a Mercy for the people who believe.

(447) Alif-Lam-Mim-Ra. [These letters are one of the miracles of the Qur'an; and none but Allah (Alone) knows their meanings]. These are the Verses of the Book (the Qur'an), and that which has been revealed unto you (Muhammad صلى الله عليه و سلم) from your Lord is the truth, but most men believe not.

(448) And if you (O Muhammad صلى الله عليه و سلم) wonder (at these polytheists who deny your message of Islamic Monotheism and have taken besides Allah others for worship who can neither harm nor benefit), then wondrous is their saying: "When we are dust, shall we indeed then be (raised) in a new creation?" They are those who disbelieved in their Lord! They are those who will have iron chains tying their hands to their necks. They will be the dwellers of the Fire to abide therein.

(449) They ask you to hasten the evil before the good, while (many) exemplary punishments have indeed occurred before them. But verily, your Lord is full of Forgiveness for mankind in spite of their wrong-doing. And verily, your Lord is (also) Severe in punishment.

(450) Allah knows what every female bears, and by how much the wombs fall short (of their time or number) or exceed. Everything with Him is in (due) proportion.
