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

(401) (They will say): "Our Lord! Remove the torment from us, really we shall become believers!"

(402) (But they were aggressive), so he [Musa (Moses)] called upon his Lord (saying): "These are indeed the people who are Mujrimun (disbelievers, polytheists, sinners, criminals)."

(403) Are they better or the people of Tubba' and those before them? We destroyed them because they were indeed Mujrimun (disbelievers, polytheists, sinners, criminals).

(404) Verily, in the heavens and the earth are signs for the believers.

(405) Say (O Muhammad صلى الله عليه و سلم) to the believers to forgive those who (harm them and) hope not for the Days of Allah (i.e. His Recompense), that He may recompense people, according to what they have earned (i.e. to punish these disbelievers who harm the believers).

(406) And to Allah belongs the kingdom of the heavens and the earth. And on the Day that the Hour will be established - on that Day the followers of falsehood (polytheists, disbelievers, worshippers of false deities) shall lose (everything).

(407) But as for those who disbelieved (it will be said to them): "Were not Our Verses recited to you? But you were proud, and you were a people who were Mujrimun (polytheists, disbelievers, sinners, criminals)."

(408) And when Our Clear Verses are recited to them, the disbelievers say of the truth (this Qur'an) when it reaches them: "This is plain magic!"

(409) Say: "Tell me! If this (Qur'an) is from Allah and you deny it, and a witness from among the Children of Israel ('Abdullah bin Salam رضي الله عنه) testifies that [this Qur'an is from Allah (like the Taurat (Torah)], and he believed (embraced Islam) while you are too proud (to believe)." Verily, Allah guides not the people who are Zalimun (polytheists, disbelievers and wrong-doers).

(410) Destroying everything by the Command of its Lord! So they became such that nothing could be seen except their dwellings! Thus do We recompense the people who are Mujrimun (polytheists, disbelievers, sinners)!
