The word(s) "believe" appears 1522 time(s) in 1179 verse(s) in Quran in Mohsin Khan translation.

(901) "Whosoever does an evil deed, will not be requited except the like thereof; and whosoever does a righteous deed, whether male or female and is a true believer (in the Oneness of Allah), such will enter Paradise, where they will be provided therein (with all things in abundance) without limit.

(902) "You invite me to disbelieve in Allah (and in His Oneness), and to join partners in worship with Him of which I have no knowledge; and I invite you to the All-Mighty, the Oft-Forgiving!

(903) They will say: "Did there not come to you, your Messengers with (clear) evidence (and signs)?" They will say: "Yes." They will reply: "Then call (as you like)! And the invocation of the disbelievers is nothing but in vain (as it will not be answered by Allah)!"

(904) Verily, We will indeed make victorious Our Messengers and those who believe (in the Oneness of Allah - Islamic Monotheism) in this world's life and on the Day when the witnesses will stand forth, (i.e. Day of Resurrection) -

(905) The Day when their excuses will be of no profit to Zalimun (polytheists, wrong-doers and disbelievers in the Oneness of Allah). Theirs will be the curse, and theirs will be the evil abode (i.e. painful torment in Hell-fire).

(906) And not equal are the blind and those who see; nor are (equal) those who believe (in the Oneness of Allah - Islamic Monotheism), and do righteous good deeds, and those who do evil. Little do you remember!

(907) Verily, the Hour (Day of Judgement) is surely coming, there is no doubt about it, yet most men believe not.

(908) And your Lord said: "Invoke Me, [i.e. believe in My Oneness (Islamic Monotheism) and ask Me for anything] I will respond to your (invocation). Verily! Those who scorn My worship [i.e. do not invoke Me, and do not believe in My Oneness, (Islamic Monotheism)] they will surely enter Hell in humiliation!"

(909) "Besides Allah"? They will say: "They have vanished from us: Nay, we did not invoke (worship) anything before." Thus Allah leads astray the disbelievers.

(910) So when they saw Our punishment, they said: "We believe in Allah Alone and reject (all) that we used to associate with Him as (His) partners.
