The word(s) "believes" appears 49 time(s) in 45 verse(s) in Quran in Mohsin Khan translation.

(11) O you who believe! Believe in Allah, and His Messenger (Muhammad صلى الله عليه وسلم), and the Book (the Qur'an) which He has sent down to His Messenger, and the Scripture which He sent down to those before (him); and whosoever disbelieves in Allah, His Angels, His Books, His Messengers, and the Last Day, then indeed he has strayed far away.

(12) Made lawful to you this day are At-Tayyibat [all kinds of Halal (lawful) foods, which Allah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables and fruits)]. The food (slaughtered cattle, eatable animals) of the people of the Scripture (Jews and Christians) is lawful to you and yours is lawful to them. (Lawful to you in marriage) are chaste women from the believers and chaste women from those who were given the Scripture (Jews and Christians) before your time when you have given their due Mahr (bridal-money given by the husband to his wife at the time of marriage), desiring chastity (i.e. taking them in legal wedlock) not committing illegal sexual intercourse, nor taking them as girl-friends. And whosoever disbelieves in Faith [i.e. in the Oneness of Allah and in all the other Articles of Faith i.e. His (Allah's) Angels, His Holy Books, His Messengers, the Day of Resurrection and Al-Qadar (Divine Preordainments)], then fruitless is his work; and in the Hereafter he will be among the losers.

(13) Allah said: "I am going to send it down unto you, but if any of you after that disbelieves, then I will punish him with a torment such as I have not inflicted on anyone among (all) the 'Alamin (mankind and jinn)."

(14) And We send not the Messengers but as givers of glad tidings and as warners. So whosoever believes and does righteous good deeds, upon such shall come no fear, nor shall they grieve.

(15) Say (O Muhammad صلى الله عليه وسلم): "O mankind! Verily, I am sent to you all as the Messenger of Allah - to Whom belongs the dominion of the heavens and the earth. La ilaha illa Huwa (none has the right to be worshipped but He). It is He Who gives life and causes death. So believe in Allah and His Messenger (Muhammad صلى الله عليه وسلم), the Prophet who can neither read nor write (i.e. Muhammad صلى الله عليه وسلم), who believes in Allah and His Words [(this Qur'an), the Taurat (Torah) and the Injeel (Gospel) and also Allah's Word: "Be!" - and he was, i.e. 'Îsa (Jesus) son of Maryam (Mary), عليهما السلام], and follow him so that you may be guided. "

(16) And among them are men who annoy the Prophet (Muhammad صلى الله عليه وسلم) and say: "He is (lending his) ear (to every news)." Say: "He listens to what is best for you; he believes in Allah, has faith in the believers, and is a mercy to those of you who believe." But those who annoy Allah's Messenger (Muhammad صلى الله عليه وسلم) will have a painful torment. [See V.33:57]

(17) And be not like her who undoes the thread which she has spun, after it has become strong, by taking your oaths as a means of deception among yourselves, lest a nation should be more numerous than another nation. Allah only tests you by this [i.e who obeys Allah and fulfils Allah's Covenant and who disobeys Allah and breaks Allah's Covenant]. And on the Day of Resurrection, He will certainly make clear to you that wherein you used to differ [i.e. a believer confesses and believes in the Oneness of Allah and in the Prophethood of Prophet Muhammad صلى الله عليه و سلم which the disbeliever denies and that is their difference amongst them in the life of this world] .

(18) And whoever is blind in this world (i.e., does not see Allah's Signs and believes not in Him), will be blind in the Hereafter, and more astray from the Path.

(19) "But as for him who believes (in Allah's Oneness) and works righteousness, he shall have the best reward, (Paradise), and we (Dhul-Qarnain) shall speak unto him mild words (as instructions)."

(20) "Therefore, let not the one who believes not therein (i.e. in the Day of Resurrection, Reckoning, Paradise and Hell.), but follows his own lusts, divert you therefrom, lest you perish.
