The word(s) "prescribed" appears 24 time(s) in 20 verse(s) in Quran in Mohsin Khan translation.

(11) And We have sent down to you (O Muhammad صلى الله عليه وسلم) the Book (this Qur'an) in truth, confirming the Scripture that came before it and Muhaymin (trustworthy in highness and a witness) over it (old Scriptures) . So judge among them by what Allah has revealed, and follow not their vain desires, diverging away from the truth that has come to you. To each among you, We have prescribed a law and a clear way. If Allah had willed, He would have made you one nation, but that (He) may test you in what He has given you; so compete in good deeds. The return of you (all) is to Allah; then He will inform you about that in which you used to differ.

(12) Say (O Muhammad صلى الله عليه وسلم): "To whom belongs all that is in the heavens and the earth?" Say: "To Allah. He has prescribed Mercy for Himself. Indeed He will gather you together on the Day of Resurrection, about which there is no doubt. Those who have lost themselves will not believe [in Allah as being the only Ilah (God), and Muhammad صلى الله عليه وسلم as being one of His Messengers, and in Resurrection].

(13) When those who believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) come to you, say: "Salamun 'Alaikum" (peace be on you); your Lord has written (prescribed) Mercy for Himself, so that if any of you does evil in ignorance, and thereafter repents and does righteous good deeds (by obeying Allah), then surely, He is Oft-Forgiving, Most Merciful.

(14) The Sabbath was only prescribed for those who differed concerning it, and verily, your Lord will judge between them on the Day of Resurrection about that wherein they used to differ.

(15) Then let them complete their prescribed duties (Manasik of Hajj) and perform their vows, and circumambulate the Ancient House (the Ka'bah at Makkah).

(16) That (Manasik- prescribed duties of Hajj is the obligation that mankind owes to Allah), and whoever honours the sacred things of Allah, then that is better for him with his Lord. The cattle are lawful to you, except those (that will be) mentioned to you (as exceptions). So shun the abomination (worshipping) of idol, and shun lying speech (false statements) -

(17) The fornicatress and the fornicator, flog each of them with a hundred stripes. Let not pity withhold you in their case, in a punishment prescribed by Allah, if you believe in Allah and the Last Day. And let a party of the believers witness their punishment. (This punishment is for unmarried persons guilty of the above crime, but if married persons commit it (illegal sex), the punishment is to stone them to death, according to Allah's Law).

(18) O you who believe! When you marry believing women, and then divorce them before you have sexual intercourse with them, no 'Iddah [divorce prescribed period, see (V.65:4)] have you to count in respect of them. So give them a present, and set them free (i.e. divorce), in a handsome manner.

(19) O Prophet (صلى الله عليه وسلم)! When you divorce women, divorce them at their 'Iddah (prescribed periods) and count (accurately) their 'Iddah (periods ). And fear Allah your Lord (O Muslims). And turn them not out of their (husband's) homes nor shall they (themselves) leave, except in case they are guilty of some open illegal sexual intercourse. And those are the set limits of Allah. And whosoever transgresses the set limits of Allah, then indeed he has wronged himself. You (the one who divorces his wife) know not it may be that Allah will afterward bring some new thing to pass (i.e. to return her back to you if that was the first or second divorce).

(20) And those of your women as have passed the age of monthly courses, for them the 'Iddah (prescribed period), if you have doubt (about their periods), is three months; and for those who have no courses [(i.e. they are still immature) their 'Iddah (prescribed period) is three months likewise, except in case of death] . And for those who are pregnant (whether they are divorced or their husbands are dead), their 'Iddah (prescribed period) is until they lay down their burden; and whosoever fears Allah and keeps his duty to Him, He will make his matter easy for him.
