The word(s) "only" appears 296 time(s) in 271 verse(s) in Quran in Mohsin Khan translation.

(101) Verily! Our Word unto a thing when We intend it, is only that We say unto it: "Be!" - and it is.

(102) And Allah said (O mankind!): "Take not ilahain (two gods in worship). Verily, He (Allah) is (the) only One Ilah (God). Then, fear Me (Allah جل جلاله) much [and Me (Alone), i.e. be away from all kinds of sins and evil deeds that Allah has forbidden and do all that Allah has ordained and worship none but Allah] .

(103) Then, if they turn away, your duty (O Muhammad صلى الله عليه و سلم) is only to convey (the Message) in a clear way.

(104) And be not like her who undoes the thread which she has spun, after it has become strong, by taking your oaths as a means of deception among yourselves, lest a nation should be more numerous than another nation. Allah only tests you by this [i.e who obeys Allah and fulfils Allah's Covenant and who disobeys Allah and breaks Allah's Covenant]. And on the Day of Resurrection, He will certainly make clear to you that wherein you used to differ [i.e. a believer confesses and believes in the Oneness of Allah and in the Prophethood of Prophet Muhammad صلى الله عليه و سلم which the disbeliever denies and that is their difference amongst them in the life of this world] .

(105) Verily! He has no power over those who believe and put their trust only in their Lord (Allah).

(106) His power is only over those who obey and follow him (Satan), and those who join partners with Him (Allah i.e. those who are Mushrikun i.e. polytheists. See Verse 6:121).

(107) And indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad صلى الله عليه و سلم)." The tongue of the man they refer to is foreign, while this (the Qur'an) is a clear Arabic tongue.

(108) It is only those who believe not in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, who fabricate falsehood, and it is they who are liars.

(109) He has forbidden you only Al-Maitah (meat of a dead animal), blood, the flesh of swine, and any animal which is slaughtered as a sacrifice for others than Allah (or has been slaughtered for idols or on which Allah's Name has not been mentioned while slaughtering). But if one is forced by necessity, without wilful disobedience, and not transgressing, - then, Allah is Oft-Forgiving, Most Merciful.

(110) 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.
