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

(281) It may be that you (O Muhammad صلى الله عليه وسلم) are going to kill yourself with grief, that they do not become believers [in your Risalah (Messengership) i.e. in your Message of Islamic Monotheism].

(282) Verily, in this is an Ayah (proof or sign), yet most of them (polytheists, pagans who do not believe in Resurrection) are not believers.

(283) "Verily we really hope that our Lord will forgive us our sins, as we are the first of the believers [in Musa (Moses) and in the Monotheism which he has brought from Allah]."

(284) Verily in this is indeed a sign (or a proof), yet most of them are not believers.

(285) (Alas!) If we only had a chance to return (to the world), we shall truly be among the believers!

(286) Verily in this is indeed a sign, yet most of them are not believers.

(287) "And I am not going to drive away the believers.

(288) Therefore judge You between me and them, and save me and those of the believers who are with me."

(289) Then We drowned the rest (disbelievers) thereafter.

(290) Verily, in this is indeed a sign, yet most of them are not believers.
