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

(431) And whenever there comes down a Surah (chapter from the Qur'an), some of them (hypocrites) say: "Which of you has had his Faith increased by it?" As for those who believe, it has increased their Faith, and they rejoice.

(432) But as for those in whose hearts is a disease (of doubt, disbelief and hypocrisy), it will add suspicion and doubt to their suspicion, disbelief and doubt; and they die while they are disbelievers.

(433) 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.

(434) Is it a wonder for mankind that We have sent Our Revelation to a man from among themselves (i.e. Prophet Muhammad صلى الله عليه وسلم) (saying): "Warn mankind (of the coming torment in Hell), and give good news to those who believe (in the Oneness of Allah and in His Prophet Muhammad صلى الله عليه وسلم) that they shall have with their Lord the rewards of their good deeds?" (But) the disbelievers say: "This is indeed an evident sorcerer (i.e. Prophet Muhammad صلى الله عليه وسلم and the Qur'an)!

(435) To Him is the return of all of you. The Promise of Allah is true. It is He Who begins the creation and then will repeat it, that He may reward with justice those who believed (in the Oneness of Allah - Islamic Monotheism) and did deeds of righteousness. But those who disbelieved will have a drink of boiling fluids and painful torment because they used to disbelieve.

(436) Verily, those who believe, and do deeds of righteousness, their Lord will guide them through their Faith; under them will flow rivers in the Gardens of Delight (Paradise).

(437) And indeed, We destroyed generations before you when they did wrong, while their Messengers came to them with clear proofs, but they were not such as to believe! Thus do We requite the people who are Mujrimun (disbelievers, polytheists, sinners, criminals).

(438) So who does more wrong than he who forges a lie against Allah or denies His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)? Surely, the Mujrimun (criminals, sinners, disbelievers and polytheists) will never be successful!

(439) Thus is the Word of your Lord justified against those who rebel (disobey Allah) that they will not believe (in the Oneness of Allah and in Muhammad صلى الله عليه وسلم as the Messenger of Allah).

(440) And of them there are some who believe therein; and of them there are some who believe not therein, and your Lord is All-Aware of the Mufsidun (evil-doers, liars).
