The word(s) "believers" appears 593 time(s) in 512 verse(s) in Quran in Mohsin Khan translation.

(321) 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].

(322) (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).

(323) 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)."

(324) 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.

(325) 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).

(326) 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]

(327) 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.

(328) And on the Day that the Hour will be established, the Mujrimun (criminals, disbelievers, polytheists, sinners) will swear that they stayed not but an hour - thus were they ever deluded [away from the truth (i.e. they used to tell lies and take false oaths, and turn away from the truth) in this life of the world)]

(329) And indeed We have set forth for mankind, in this Qur'an every kind of parable. But if you (O Muhammad صلى الله عليه وسلم) bring to them any sign or proof (as an evidence for the truth of your Prophethood), the disbelievers are sure to say (to the believers): "You follow nothing but falsehood, and magic."

(330) And if you only could see when the Mujrimun (criminals, disbelievers, polytheists, sinners) shall hang their heads before their Lord (saying): "Our Lord! We have now seen and heard, so send us back (to the world), that we will do righteous good deeds. Verily! We now believe with certainty."
