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

(371) And they (Arab pagans) wonder that a warner (Prophet Muhammad صلى الله عليه وسلم) has come to them from among themselves. And the disbelievers say: "This (Prophet Muhammad صلى الله عليه وسلم) is a sorcerer, a liar.

(372) Shall We treat those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds as Mufsidun (those who associate partners in worship with Allah and commit crimes) on earth? Or shall We treat the Muttaqun (the pious - See V.2:2) as the Fujjar (criminals, disbelievers, the wicked)?

(373) This is so! And for the Taghun (transgressors, the disobedient to Allah and His Messenger - disbelievers in the Oneness of Allah, criminals) will be an evil final return (Fire).

(374) Except Iblis (Satan): he was proud and was one of the disbelievers.

(375) "Except Your chosen slaves amongst them (i.e. faithful, obedient, true believers of Islamic Monotheism)."

(376) If you disbelieve, then verily, Allah is not in need of you; He likes not disbelief for His slaves. And if you are grateful (by being believers), He is pleased therewith for you. No bearer of burdens shall bear the burden of another. Then to your Lord is your return, and He will inform you what you used to do. Verily, He is the All-Knower of that which is in (men's) breasts.

(377) Then, who does more wrong than one who utters a lie against Allah, and denies the truth [this Qur'an, the Prophet (Muhammad صلى الله عليه وسلم) and the Islamic Monotheism] when it comes to him! Is there not in Hell an abode for the disbelievers?

(378) And he (Muhammad صلى الله عليه وسلم) who has brought the truth (this Qur'an and Islamic Monotheism) and (those who) believed therein (i.e. the true believers of Islamic Monotheism), those are Al-Muttaqun (the pious - See V.2:2).

(379) 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. "

(380) 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.
