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

(441) Say: "Tell me, if His torment should come to you by night or by day, which portion thereof would the Mujrimun (disbelievers, polytheists, sinners, criminals) hasten on ?"

(442) Is it then that when it has actually befallen, you will believe in it? What! Now (you believe)? And you used (aforetime) to hasten it on!"

(443) O mankind! There has come to you a good advice from your Lord (i.e. the Qur'an, enjoining all that is good and forbidding all that is evil), and a healing for that (disease of ignorance, doubt, hypocrisy and differences) which is in your breasts, - a guidance and a mercy (explaining lawful and unlawful things) for the believers.

(444) No doubt! Verily, the Auliya' of Allah [i.e. those who believe in the Oneness of Allah and fear Allah much (abstain from all kinds of sins and evil deeds which he has forbidden), and love Allah much (perform all kinds of good deeds which He has ordained)], no fear shall come upon them nor shall they grieve.

(445) Those who believed (in the Oneness of Allah - Islamic Monotheism), and used to fear Allah much (by abstaining from evil deeds and sins and by doing righteous deeds).

(446) (A brief) enjoyment in this world! - and then unto Us will be their return, then We shall make them taste the severest torment because they used to disbelieve [in Allah, belie His Messengers, deny and challenge His Ayat (proofs, signs, verses, etc.)].

(447) Then after him We sent Messengers to their people. They brought them clear proofs, but they would not believe what they had already rejected beforehand. Thus We seal the hearts of the transgressors (those who disbelieve in the Oneness of Allah and disobey Him).

(448) Then after them We sent Musa (Moses) and Harun (Aaron) to Fir'aun (Pharaoh) and his chiefs with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). But they behaved arrogantly and were Mujrimun (disbelievers, sinners, polytheists, criminals) folk.

(449) They said: "Have you come to us to turn us away from that (Faith) we found our fathers following, and that you two may have greatness in the land? We are not going to believe you two!"

(450) "And Allah will establish and make apparent the truth by His Words, however much the Mujrimun (criminals, disbelievers, polytheists, sinners) may hate it."
