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

(881) And verily, if you ask them: "Who created the heavens and the earth?" Surely they will say: "Allah (has created them)." Say: "Tell me then, the things that you invoke besides Allah - if Allah intended some harm for me, could they remove His harm? Or if He (Allah) intended some mercy for me, could they withhold His Mercy?" Say: "Sufficient for me is Allah; in Him those who trust (i.e. believers) must put their trust. "

(882) And when Allah Alone is mentioned, the hearts of those who believe not in the Hereafter are filled with disgust (from the Oneness of Allah توحيد الله) and when those (whom they obey or worship) besides Him [like all false deities other than Allah, - it may be a Messenger, an angel, a pious man, a jinni, or any other creature even idols, graves of religious people, saints, priests, monks and others.] are mentioned, behold, they rejoice!

(883) And those who did wrong (the polytheists and disbelievers in the Oneness of Allah), if they had all that is in earth and therewith as much again, they verily, would offer it to ransom themselves therewith on the Day of Resurrection from the evil torment; and there will become apparent to them from Allah what they had not been reckoning.

(884) Do they not know that Allah enlarges the provision for whom He wills, and straitens it (for whom He wills). Verily, in this are signs for the folk who believe!

(885) Lest a person should say: "Alas, my grief that I was undutiful to Allah (i.e. I have not done what Allah has ordered me to do), and I was indeed among those who mocked [at the truth! i.e. La ilaha illallah (none has the right to be worshipped but Allah), the Qur'an, and Muhammad صلى الله عليه وسلم and at the faithful believers]

(886) Yes! Verily, there came to you My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and you denied them, and were proud and were among the disbelievers.

(887) To Him belong the keys of the heavens and the earth. And those who disbelieve in the Ayat (proofs, evidence, verses, signs, revelations, etc.) of Allah, such are they who will be the losers.

(888) And those who disbelieved will be driven to Hell in groups till, when they reach it, the gates thereof will be opened (suddenly like a prison at the arrival of the prisoners). And its keepers will say, "Did not the Messengers come to you from yourselves, reciting to you the Verses of your Lord, and warning you of the Meeting of this Day of yours?" They will say: "Yes, but the Word of torment has been justified against the disbelievers!"

(889) None disputes in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah but those who disbelieve. So let not their ability of going about here and there through the land (for their purposes) deceive you [O Muhammad صلى الله عليه وسلم, for their ultimate end will be the Fire of Hell]!

(890) Thus has the Word of your Lord been justified against those who disbelieved, that they will be the dwellers of the Fire.
