The word(s) "believer" appears 651 time(s) in 556 verse(s) in Quran in Mohsin Khan translation.

(521) So he (the disbeliever) neither believed (in this Qur'an and in the Message of Muhammad صلى الله عليه وسلم) nor prayed!

(522) Woe to you [O man (disbeliever)]! And then (again) woe to you!

(523) Again, woe to you [O man (disbeliever)]! And then (again) woe to you!

(524) Verily, We have prepared for the disbelievers iron chains, iron collars, and a blazing Fire.

(525) Verily,, the Abrar (the pious believers of Islamic Monotheism), shall drink of a cup mixed with (water from a spring in Paradise called) Kafur

(526) Therefore be patient (O Muhammad صلى الله عليه وسلم) with constancy to the Command of your Lord (Allah, by doing your duty to Him and by conveying His Message to mankind), and obey neither a sinner nor a disbeliever among them.

(527) Verily, these (disbelievers) love the present life of this world, and put behind them a heavy Day (that will be hard).

(528) Thus do We deal with the Mujrimun (polytheists, disbelievers, sinners, criminals).

(529) (It will be said to the disbelievers): "Depart you to that which you used to deny!

(530) (O you disbelievers)! Eat and enjoy yourselves (in this worldly life) for a little while. Verily, you are the Mujrimun (polytheists, disbelievers, sinners, criminals).
