The word(s) "believe" appears 1522 time(s) in 1179 verse(s) in Quran in Mohsin Khan translation.

(811) And obey not the disbelievers and the hypocrites, and harm them not (in revenge for their harming you till you are ordered). And put your trust in Allah, and Sufficient is Allah as a Wakil (Trustee, or Disposer of affairs). [Tafsir Al-Qurtubi]

(812) O you who believe! When you marry believing women, and then divorce them before you have sexual intercourse with them, no 'Iddah [divorce prescribed period, see (V.65:4)] have you to count in respect of them. So give them a present, and set them free (i.e. divorce), in a handsome manner.

(813) O Prophet (Muhammad صلى الله عليه وسلم)! Verily, We have made lawful to you your wives, to whom you have paid their Mahr (bridal-money given by the husband to his wife at the time of marriage), and those (slaves) whom your right hand possesses - whom Allah has given to you, and the daughters of your 'Amm (paternal uncles) and the daughters of your 'Ammat (paternal aunts) and the daughters of your Khal (maternal uncles) and the daughters of your Khalat (maternal aunts) who migrated (from Makkah) with you, and a believing woman if she offers herself to the Prophet, and the Prophet wishes to marry her - a privilege for you only, not for the (rest of) the believers. Indeed We know what We have enjoined upon them about their wives and those (slaves) whom their right hands possess, in order that there should be no difficulty on you. And Allah is Ever Oft-Forgiving, Most Merciful.

(814) O you who believe! Enter not the Prophet's houses, unless permission is given to you for a meal, (and then) not (so early as) to wait for its preparation. But when you are invited, enter, and when you have taken your meal, disperse without sitting for a talk. Verily, such (behaviour) annoys the Prophet, and he is shy of (asking) you (to go); but Allah is not shy of (telling you) the truth. And when you ask (his wives) for anything you want, ask them from behind a screen: that is purer for your hearts and for their hearts. And it is not (right) for you that you should annoy Allah's Messenger, nor that you should ever marry his wives after him (his death). Verily, with Allah that shall be an enormity.

(815) Allah sends His Salat (Graces, Honours, Blessings, Mercy) on the Prophet (Muhammad صلى الله عليه وسلم), and also His angels (ask Allah to bless and forgive him). O you who believe! Send your Salat on (ask Allah to bless) him (Muhammad صلى الله عليه وسلم), and (you should) greet (salute) him with the Islamic way of greeting (salutation i.e. As-Salamu 'Alaikum ).

(816) O Prophet! Tell your wives and your daughters and the women of the believers to draw their cloaks (veils) all over their bodies (i.e. screen themselves completely except the eyes or one eye to see the way). That will be better, that they should be known (as free respectable women) so as not to be annoyed. And Allah is Ever Oft-Forgiving, Most Merciful.

(817) Verily, Allah has cursed the disbelievers, and has prepared for them a flaming Fire (Hell).

(818) O you who believe! Be not like those who annoyed Musa (Moses), but Allah cleared him of that which they alleged, and he was honourable before Allah.

(819) O you who believe! Keep your duty to Allah and fear Him, and speak (always) the truth.

(820) So that Allah will punish the hypocrites, men and women, and the men and women who are Al-Mushrikun (polytheists, idolaters, pagans, disbelievers, in the Oneness of Allah, and His Messenger Muhammad صلى الله عليه وسلم). And Allah will pardon (accept the repentance of) the true believers of the Islamic Monotheism, men and women. And Allah is Ever Oft-Forgiving, Most Merciful.
