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

(521) The parable of those who disbelieved in their Lord is that their works are as ashes, on which the wind blows furiously on a stormy day; they shall not be able to get aught of what they have earned. That is the straying, far away (from the Right Path).

(522) And those who believed (in the Oneness of Allah and His Messengers and whatever they brought) and did righteous deeds, will be made to enter Gardens under which rivers flow, - to dwell therein for ever (i.e. in Paradise), with the Permission of their Lord. Their greeting therein will be: Salam (peace!).

(523) Allah will keep firm those who believe, with the word that stands firm in this world (i.e. they will keep on worshipping Allah Alone and none else), and in the Hereafter. And Allah will cause to go astray those who are Zalimun (polytheists and wrong-doers), and Allah does what He wills.

(524) Say (O Muhammad صلى الله عليه و سلم) to 'Ibadi (My slaves) who have believed, that they should perform As-Salat (Iqamat-as-Salat ), and spend in charity out of the sustenance We have given them, secretly and openly, before the coming of a Day on which there will be neither mutual bargaining nor befriending.

(525) And He gave you of all that you asked for, and if you count the Blessings of Allah, never will you be able to count them. Verily, man is indeed an extreme wrong-doer, a disbeliever (an extreme ingrate who denies Allah's Blessings by disbelief, and by worshipping others besides Allah, and by disobeying Allah and His Prophet Muhammad صلى الله عليه و سلم).

(526) "Our Lord! Forgive me and my parents, and (all) the believers on the Day when the reckoning will be established."

(527) And you will see the Mujrimun (criminals, disbelievers in the Oneness of Allah - Islamic Monotheism, polytheists) that Day Muqarranun (bound together) in fetters.

(528) How much would those who disbelieved wish that they had been Muslims [those who have submitted themselves to Allah's Will in Islam i.e. Islamic Monotheism - this will be on the Day of Resurrection when they will see the disbelievers going to Hell and the Muslims going to Paradise].

(529) We send not the angels down except with the truth (i.e. for torment), and in that case, they (the disbelievers) would have no respite!

(530) They would not believe in it (the Qur'an); and already the example of (Allah's punishment of) the ancients (who disbelieved) has gone forth.
