The word(s) "appoint" appears 75 time(s) in 74 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) It is He who doth take your souls by night, and hath knowledge of all that ye have done by day: by day doth He raise you up again; that a term appointed be fulfilled; In the end unto Him will be your return; then will He show you the truth of all that ye did.

(12) One day will He gather them all together, (and say): "O ye assembly of Jinns! Much (toll) did ye take of men." Their friends amongst men will say: "Our Lord! we made profit from each other: but (alas!) we reached our term - which thou didst appoint for us." He will say: "The Fire be your dwelling-place: you will dwell therein for ever, except as Allah willeth." for thy Lord is full of wisdom and knowledge.

(13) Thy Lord is self-sufficient, full of Mercy: if it were His will, He could destroy you, and in your place appoint whom He will as your successors, even as He raised you up from the posterity of other people.

(14) To every people is a term appointed: when their term is reached, not an hour can they cause delay, nor (an hour) can they advance (it in anticipation).

(15) Who is more unjust than one who invents a lie against Allah or rejects His Signs? For such, their portion appointed must reach them from the Book (of decrees): until, when our messengers (of death) arrive and take their souls, they say: "Where are the things that ye used to invoke besides Allah?" They will reply, "They have left us in the lurch," And they will bear witness against themselves, that they had rejected Allah.

(16) We appointed for Moses thirty nights, and completed (the period) with ten (more): thus was completed the term (of communion) with his Lord, forty nights. And Moses had charged his brother Aaron (before he went up): "Act for me amongst my people: Do right, and follow not the way of those who do mischief."

(17) When Moses came to the place appointed by Us, and his Lord addressed him, He said: "O my Lord! show (Thyself) to me, that I may look upon thee." Allah said: "By no means canst thou see Me (direct); But look upon the mount; if it abide in its place, then shalt thou see Me." When his Lord manifested His glory on the Mount, He made it as dust. And Moses fell down in a swoon. When he recovered his senses he said: "Glory be to Thee! to Thee I turn in repentance, and I am the first to believe."

(18) They ask thee about the (final) Hour - when will be its appointed time? Say: "The knowledge thereof is with my Lord (alone): None but He can reveal as to when it will occur. Heavy were its burden through the heavens and the earth. Only, all of a sudden will it come to you." They ask thee as if thou Wert eager in search thereof: Say: "The knowledge thereof is with Allah (alone), but most men know not."

(19) Remember ye were on the hither side of the valley, and they on the farther side, and the caravan on lower ground than ye. Even if ye had made a mutual appointment to meet, ye would certainly have failed in the appointment: But (thus ye met), that Allah might accomplish a matter already enacted; that those who died might die after a clear Sign (had been given), and those who lived might live after a Clear Sign (had been given). And verily Allah is He Who heareth and knoweth (all things).

(20) Say: "I have no power over any harm or profit to myself except as Allah willeth. To every people is a term appointed: when their term is reached, not an hour can they cause delay, nor (an hour) can they advance (it in anticipation)."
