The word(s) "appoint" appears 84 time(s) in 80 verse(s) in Quran in Mohsin Khan translation.

(61) He has created the heavens and the earth with truth. He makes the night to go in the day and makes the day to go in the night. And He has subjected the sun and the moon. Each running (on a fixed course) for an appointed term. Verily, He is the All-Mighty, the Oft-Forgiving.

(62) It is Allah Who takes away the souls at the time of their death, and those that die not during their sleep. He keeps those (souls) for which He has ordained death and sends the rest for a term appointed. Verily, in this are signs for a people who think deeply.

(63) It is He, Who has created you (Adam) from dust, then from a Nutfah [mixed semen drops of male and female sexual discharge (i.e. Adam's offspring)] then from a clot (a piece of coagulated blood), then brings you forth as an infant, then (makes you grow) to reach the age of full strength, and afterwards to be old (men and women)- though some among you die before,- and that you reach an appointed term in order that you may understand.

(64) And they divided not till after knowledge had come to them, through (selfish) transgression between themselves. And had it not been for a Word that went forth before from your Lord for an appointed term, the matter would have been settled between them. And verily, those who were made to inherit the Scripture [i.e. the Taurah (Torah) and the Injeel (Gospel)] after them (i.e. Jews and Christians) are in grave doubt concerning it (i.e. Allah's true religion - Islam or the Qur'an).

(65) And Who has created all the pairs and has appointed for you ships and cattle on which you ride:

(66) And whosoever turns away blindly from the remembrance of the Most Gracious (Allah) (i.e. this Qur'an and worship of Allah), We appoint for him Shaitan (Satan - devil) to be a Qarin (a companion) to him.

(67) And ask (O Muhammad صلى الله عليه و سلم) those of Our Messengers whom We sent before you: "Did We ever appoint alihah (gods) to be worshipped besides the Most Gracious (Allah)?"

(68) Or do they think that We hear not their secrets and their private counsel? (Yes We do) and Our messengers (appointed angels in charge of mankind) are by them, to record.

(69) Verily, the Day of Judgement (when Allah will judge between the creatures) is the time appointed for all of them -

(70) We created not the heavens and the earth and all that is between them except with truth, and for an appointed term. But those who disbelieve turn away from that whereof they are warned.
