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

(771) And as for those who disbelieved and belied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, Allah's Messengers, Resurrection, etc.), and the Meeting of the Hereafter, such shall be brought forth to the torment (in the Hell-fire).

(772) So glorify Allah [above all that (evil) they associate with Him (O believers)] when you come up to the evening [i.e. offer the (Maghrib ) sunset and ('Isha') night prayers], and when you enter the morning [i.e. offer the (Fajr) morning prayer].

(773) (And remain always) turning in repentance to Him (only), and be afraid and dutiful to Him; and perform As-Salat (Iqamat-as-Salat) and be not of Al-Mushrikun (the polytheists, idolaters, disbelievers in the Oneness of Allah).

(774) Do they not see that Allah enlarges the provision for whom He wills and straitens (it for whom He wills). Verily, in that are indeed signs for a people who believe.

(775) Say (O Muhammad صلى الله عليه وسلم): "Travel in the land and see what was the end of those before (you)! Most of them were Mushrikun (polytheists, idolaters, disbelievers in the Oneness of Allah)."

(776) Whosoever disbelieves will suffer from his disbelief, and whosoever does righteous good deeds (by practising Islamic Monotheism), then such will prepare a good place (in Paradise) for themselves (and will be saved by Allah from His Torment).

(777) That He may reward those who believe (in the Oneness of Allah - Islamic Monotheism), and do righteous good deeds, out of His Bounty. Verily, He likes not the disbelievers.

(778) And indeed We did send Messengers before you (O Muhammad صلى الله عليه وسلم) to their own peoples. They came to them with clear proofs, then, We took vengeance on those who committed crimes (disbelief, setting partners in worship with Allah, sins); and (as for) the believers, it was incumbent upon Us to help (them).

(779) And if We send a wind [which would spoil the green growth (tilth) brought up by the previous rain], and they see (their tilth) turn yellow - behold, they then (after their being glad,) would become unthankful (to their Lord Allah as) disbelievers. [Tafsir At-Tabari]

(780) So verily, you (O Muhammad صلى الله عليه وسلم) cannot make the dead to hear (i.e. the disbelievers), nor can you make the deaf to hear the call, when they show their backs and turn away.
