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

(241) "Verily, My slaves (i.e. the true believers of Islamic Monotheism) - you have no authority over them. And All-Sufficient is your Lord as a Guardian."

(242) And when We bestow Our Grace on man (the disbeliever), he turns away and becomes arrogant (far away from the Right Path). And when evil touches him, he is in great despair.

(243) Say (to the disbelievers): "If you possessed the treasure of the Mercy of my Lord (wealth, money, provision.), then you would surely hold back (from spending) for fear of (being exhausted), and man is ever miserly!"

(244) (He has made it) straight to give warning (to the disbelievers) of a severe punishment from Him, and to give glad tidings to the believers (in the Oneness of Allah - Islamic Monotheism), who do righteous deeds, that they shall have a fair reward (i.e. Paradise).

(245) And thus We made their case known (to the people), that they might know that the Promise of Allah is true, and that there can be no doubt about the Hour. (Remember) when they (the people of the city) disputed among themselves about their case, they said: "Construct a building over them; their Lord knows best about them;" (then) those who won their point said (most probably the disbelievers): "We verily shall build a place of worship over them."

(246) And say: "The truth is from your Lord." Then whosoever wills, let him believe; and whosoever wills, let him disbelieve. Verily, We have prepared for the Zalimun (polytheists and wrong-doers.), a Fire whose walls will be surrounding them (disbelievers in the Oneness of Allah). And if they ask for help (relief, water), they will be granted water like boiling oil, that will scald their faces. Terrible is the drink, and an evil Murtafaq (dwelling, resting place.)!

(247) And the Book (one's Record) will be placed (in the right hand for a believer in the Oneness of Allah, and in the left hand for a disbeliever in the Oneness of Allah), and you will see the Mujrimun (criminals, polytheists, sinners), fearful of that which is (recorded) therein. They will say: "Woe to us! What sort of Book is this that leaves neither a small thing nor a big thing, but has recorded it with numbers!" And they will find all that they did, placed before them, and your Lord treats no one with injustice.

(248) "And as for the boy, his parents were believers, and we feared lest he should oppress them by rebellion and disbelief.

(249) He said: "As for him (a disbeliever in the Oneness of Allah) who does wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with a terrible torment (Hell).

(250) And on that Day We shall present Hell to the disbelievers, plain to view -
