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

(41) [Zakariyya (Zachariah)] said: "My Lord! appoint for me a sign." He said: "Your sign is that you shall not speak unto mankind for three nights, though having no bodily defect."

(42) He said: "So (it will be), your Lord said: 'That is easy for Me (Allah): And (We wish) to appoint him as a sign to mankind and a mercy from Us (Allah), and it is a matter (already) decreed, (by Allah).' "

(43) "And appoint for me a helper from my family,

(44) "Then verily, we can produce magic the like thereof; so appoint a meeting between us and you, which neither we nor you shall fail to keep, in an open place where both shall have a just and equal chance (and beholders could witness the competition)."

(45) [Musa (Moses)] said: "Your appointed meeting is the day of the festival, and let the people assemble when the sun has risen (forenoon)."

(46) O mankind! If you are in doubt about the Resurrection, then verily We have created you (i.e. Adam) from dust, then from a Nutfah (mixed drops of male and female sexual discharge i.e. the offspring of Adam), then from a clot (a piece of thick coagulated blood) then from a little lump of flesh - some formed and some unformed (as in the case of miscarriage) - that We may make (it) clear to you (i.e. to show you Our Power and Ability to do what We will). And We cause whom We will to remain in the wombs for an appointed term, then We bring you out as infants, then (give you growth) that you may reach your age of full strength. And among you there is he who dies (young), and among you there is he who is brought back to the miserable old age, so that he knows nothing after having known. And you see the earth barren, but when We send down water (rain) on it, it is stirred (to life), and it swells and puts forth every lovely kind (of growth).

(47) That they may witness things that are of benefit to them (i.e. reward of Hajj in the Hereafter, and also some worldly gain from trade), and mention the Name of Allah on appointed days (i.e. 10th, 11th, 12th, and 13th day of Dhul-Hijjah), over the beast of cattle that He has provided for them (for sacrifice), [at the time of their slaughtering by saying: (Bismillah, Wallahu-Akbar, Allahumma Minka wa Ilaik).] Then eat thereof and feed therewith the poor having a hard time.

(48) In them (cattle offered for sacrifice) are benefits for you for an appointed term, and afterwards they are brought for sacrifice unto the ancient House (the Haram - sacred territory of Makkah).

(49) And for every nation We have appointed religious ceremonies, that they may mention the Name of Allah over the beast of cattle that He has given them for food. And your Ilah (God) is One Ilah (God - Allah), so you must submit to Him Alone (in Islam). And (O Muhammad صلى الله عليه وسلم) give glad tidings to the Mukhbitun (those who obey Allah with humility and are humble from among the true believers of Islamic Monotheism),

(50) Or [the state of a disbeliever] is like the darkness in a vast deep sea, overwhelmed with waves topped by waves, topped by dark clouds, (layers of) darkness upon darkness: if a man stretches out his hand, he can hardly see it! And he for whom Allah has not appointed light, for him there is no light.
