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

(121) So We have made this (the Qur'an) easy in your own tongue (O Muhammad صلى الله عليه وسلم), only that you may give glad tidings to the Muttaqun (the pious - See V.2:2), and warn with it the Ludd (most quarrelsome) people.

(122) But only as a Reminder to those who fear (Allah).

(123) "And throw that which is in your right hand! It will swallow up that which they have made. That which they have made is only a magician's trick, and the magician will never be successful, to whatever amount (of skill) he may attain."

(124) They said: "We prefer you not over what have come to us of the clear signs and to Him (Allah) Who created us. So decree whatever you desire to decree, for you can only decree (regarding) this life of the world.

(125) Your Ilah (God) is only Allah, (the One) La ilaha illa Huwa (none has the right to be worshipped but He). He has full knowledge of all things.

(126) And if We had destroyed them with a torment before this (i.e. Messenger Muhammad صلى الله عليه وسلم and the Qur'an), they would surely have said: "Our Lord! If only You had sent us a Messenger, we should certainly have followed Your Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), before we were humiliated and disgraced."

(127) If only those who disbelieved knew (the time) when they will not be able to ward off the Fire from their faces, nor from their backs, and they will not be helped.

(128) Say (O Muhammad صلى الله عليه وسلم): "I warn you only by the revelation (from Allah and not by the opinion of the religious scholars and others). But the deaf (who follow the religious scholars and others blindly) will not hear the call, (even) when they are warned [i.e. one should follow only the Qur'an and the Sunnah (legal ways, orders, acts of worship, and the statements of Prophet Muhammad صلى الله عليه وسلم, as the companions of the Prophet صلى الله عليه وسلم did)] .

(129) Say (O Muhammad صلى الله عليه وسلم): "It is revealed to me that your Ilah (God) is only one Ilah (God - Allah). Will you then submit to His Will (become Muslims and stop worshipping others besides Allah)?"

(130) Those who have been expelled from their homes unjustly only because they said: "Our Lord is Allah." For had it not been that Allah checks one set of people by means of another, monasteries, churches, synagogues, and mosques, wherein the Name of Allah is mentioned much would surely have been pulled down. Verily, Allah will help those who help His (Cause). Truly, Allah is All-Strong, All-Mighty.
