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

(291) So they belied him, and We destroyed them. Verily in this is indeed a sign, yet most of them are not believers.

(292) So the torment overtook them. Verily, in this is indeed a sign, yet most of them are not believers.

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

(296) A guide (to the Right Path) and glad tidings for the believers [who believe in the Oneness of Allah (i.e. Islamic Monotheism)].

(297) And they belied them (those Ayat) wrongfully and arrogantly, though their ownselves were convinced thereof [i.e. those (Ayat ) are from Allah, and Musa (Moses) is the Messenger of Allah in truth, but they disliked to obey Musa (Moses), and hated to believe in his Message of Monotheism]. So see what was the end of the Mufsidun (disbelievers, disobedient to Allah, evil-doers and liars.).

(298) "Be you not exalted against me, but come to me as Muslims (true believers who submit to Allah with full submission).' "

(299) And indeed We sent to Thamud their brother Salih, saying: "Worship Allah (Alone and none else). Then look! They became two parties (believers and disbelievers) quarreling with each other."

(300) And they (the disbelievers in the Oneness of Allah) say: "When (will) this promise (be fulfilled), if you are truthful?"
