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

(281) So As-Saihah (torment - awful cry) overtook them in truth (with justice), and We made them as rubbish of dead plants. So away with the people who are Zalimun (polytheists, wrong-doers, disbelievers in the Oneness of Allah, disobedient to His Messengers).

(282) Or say they: There is madness in him? Nay, but he brought them the truth [i.e. Tauhid: Worshipping Allah Alone in all aspects, the Qur'an and the religion of Islam], but most of them (the disbelievers) are averse to the truth.

(283) Nay, but We have brought them the truth (Islamic Monotheism), and verily, they (disbelievers) are liars.

(284) And whoever invokes (or worships), besides Allah, any other ilah (god), of whom he has no proof; then his reckoning is only with his Lord. Surely! Al-Kafirun (the disbelievers in Allah and in the Oneness of Allah, polytheists, pagans, idolaters) will not be successful.

(285) The fornicatress and the fornicator, flog each of them with a hundred stripes. Let not pity withhold you in their case, in a punishment prescribed by Allah, if you believe in Allah and the Last Day. And let a party of the believers witness their punishment. (This punishment is for unmarried persons guilty of the above crime, but if married persons commit it (illegal sex), the punishment is to stone them to death, according to Allah's Law).

(286) The adulterer-fornicator marries not but an adulteress-fornicatress or a Mushrikah, and the adulteress-fornicatress none marries her except an adulterer-fornicator or a Muskrik [and that means that the man who agrees to marry (have a sexual relation with) a Mushrikah (female polytheist, pagan or idolatress) or a prostitute, then surely he is either an adulterer-fornicator, or a Mushrik (polytheist, pagan or idolater). And the woman who agrees to marry (have a sexual relation with) a Mushrik (polytheist, pagan or idolater) or an adulterer-fornicator, then she is either a prostitute or a Mushrikah (female polytheist, pagan, or idolatress)]. Such a thing is forbidden to the believers (of Islamic Monotheism).

(287) Why then, did not the believers, men and women, when you heard it (the slander), think good of their own people and say: "This (charge) is an obvious lie ?"

(288) Allah forbids you from it and warns you not to repeat the like of it forever, if you are believers.

(289) Verily, those who accuse chaste women, who never even think of anything touching their chastity and are good believers - are cursed in this life and in the Hereafter, and for them will be a great torment -

(290) And tell the believing women to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts) and not to show off their adornment except only that which is apparent (like both eyes for necessity to see the way, or outer palms of hands or one eye or dress like veil, gloves, head-cover, apron, etc.), and to draw their veils all over Juyubihinna (i.e. their bodies, faces, necks and bosoms) and not to reveal their adornment except to their husbands, or their fathers, or their husband's fathers, or their sons, or their husband's sons, or their brothers or their brother's sons, or their sister's sons, or their (Muslim) women (i.e. their sisters in Islam), or the (female) slaves whom their right hands possess, or old male servants who lack vigour, or small children who have no sense of feminine sex. And let them not stamp their feet so as to reveal what they hide of their adornment. And all of you beg Allah to forgive you all, O believers, that you may be successful.
