The word(s) "unto" appears 218 time(s) in 201 verse(s) in Quran in Mohsin Khan translation.

(81) And (He did forgive also) the three [who did not join the Tabuk expedition whose case was deferred (by the Prophet صلى الله عليه وسلم)] (for Allah's Decision) till for them the earth, vast as it is, was straitened and their ownselves were straitened to them, and they perceived that there is no fleeing from Allah, and no refuge but with Him. Then, He forgave them (accepted their repentance), that they might beg for His pardon [repent (unto Him)] Verily, Allah is the One Who forgives and accepts repentance, Most Merciful.

(82) Verily, there has come unto you a Messenger (Muhammad صلى الله عليه وسلم) from amongst yourselves (i.e. whom you know well). It grieves him that you should receive any injury or difficulty. He (Muhammad صلى الله عليه وسلم) is anxious over you (to be rightly guided, to repent to Allah, and beg Him to pardon and forgive your sins in order that you may enter Paradise and be saved from the punishment of the Hell-fire); for the believers (he صلى الله عليه وسلم is) full of pity, kind, and merciful.

(83) And when Our clear Verses are recited unto them, those who hope not for their meeting with Us, say: "Bring us a Qur'an other than this, or change it." Say (O Muhammad صلى الله عليه وسلم): "It is not for me to change it on my own accord; I only follow that which is revealed unto me. Verily, I fear the torment of the Great Day (i.e. the Day of Resurrection) if I were to disobey my Lord."

(84) But when He delivers them, behold! they rebel (disobey Allah) in the earth wrongfully. O mankind! Your rebellion (disobedience to Allah) is only against your ownselves, - a brief enjoyment of this worldly life, then (in the end) unto Us is your return, and We shall inform you of that which you used to do.

(85) Or do they say: "He (Muhammad صلى الله عليه وسلم) has forged it?" Say: "Bring then a Surah (chapter) like unto it, and call upon whomsoever you can besides Allah, if you are truthful!"

(86) Whether We show you (in your lifetime, O Muhammad صلى الله عليه وسلم) some of what We promise them (the torment), or We cause you to die - still unto Us is their return, and moreover, Allah is Witness over what they used to do.

(87) And if every person who had wronged (by disbelieving in Allah and by worshipping others besides Allah) possessed all that is on the earth and sought to ransom himself therewith (it will not be accepted), and they would feel in their hearts regret when they see the torment, and they will be judged with justice, and no wrong will be done unto them.

(88) (A brief) enjoyment in this world! - and then unto Us will be their return, then We shall make them taste the severest torment because they used to disbelieve [in Allah, belie His Messengers, deny and challenge His Ayat (proofs, signs, verses, etc.)].

(89) So if you (O Muhammad صلى الله عليه وسلم) are in doubt concerning that which We have revealed unto you, [i.e. that your name is written in the Taurat (Torah) and the Injeel (Gospel)], then ask those who are reading the Book [the Taurat (Torah) and the Injeel (Gospel)] before you. Verily, the truth has come to you from your Lord. So be not of those who doubt (it).

(90) And (O Muhammad صلى الله عليه وسلم), follow the revelation sent unto you, and be patient till Allah gives judgement. And He is the Best of judges.
