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

(201) Because of their breaking the covenant, and of their rejecting the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, and of their killing the Prophets unjustly, and of their saying: "Our hearts are wrapped (with coverings, i.e. we do not understand what the Messengers say)" - nay, Allah has set a seal upon their hearts because of their disbelief, so they believe not but a little.

(202) And there is none of the people of the Scripture (Jews and Christians) but must believe in him ['Îsa (Jesus), son of Maryam (Mary), as only a Messenger of Allah and a human being] before his ['Îsa (Jesus) عليه السلام) or a Jew's or a Christian's] death (at the time of the appearance of the angel of death). And on the Day of Resurrection, he ['Îsa (Jesus)] will be a witness against them.

(203) And their taking of Riba (usury) though they were forbidden from taking it and their devouring of men's substance wrongfully (bribery). And We have prepared for the disbelievers among them a painful torment.

(204) But those among them who are well-grounded in knowledge, and the believers, believe in what has been sent down to you (Muhammad صلى الله عليه وسلم) and what was sent down before you; and those who perform As-Salat (Iqamat-as-Salat ), and give Zakat and believe in Allah and in the Last Day, it is they to whom We shall give a great reward.

(205) Verily, those who disbelieve [by concealing the truth about Prophet Muhammad صلى الله عليه وسلم and his message of true Islamic Monotheism written in the Taurat (Torah) and the Injeel (Gospel) with them] and prevent (mankind) from the Path of Allah (Islamic Monotheism); they have certainly strayed far away. (Tafsir Al-Qurtubi).

(206) Verily, those who disbelieve and did wrong [by concealing the truth about Prophet Muhammad صلى الله عليه وسلم and his message of true Islamic Monotheism written in the Taurat (Torah) and the Injeel (Gospel) with them]; Allah will not forgive them, nor will He guide them to any way - (Tafsir Al-Qurtubi).

(207) O mankind! Verily, there has come to you the Messenger (Muhammad صلى الله عليه وسلم) with the truth from your Lord. So believe in him, it is better for you. But if you disbelieve, then certainly to Allah belongs all that is in the heavens and the earth. And Allah is Ever All-Knowing, All-Wise.

(208) O people of the Scripture (Christians)! Do not exceed the limits in your religion, nor say of Allah aught but the truth. The Messiah 'Îsa (Jesus), son of Maryam (Mary), was (no more than) a Messenger of Allah and His Word, ("Be!" - and he was) which He bestowed on Maryam (Mary) and a spirit (Ruh ) created by Him; so believe in Allah and His Messengers. Say not: "Three (trinity)!" Cease! (it is) better for you. For Allah is (the only) One Ilah (God), glory be to Him (Far Exalted is He) above having a son. To Him belongs all that is in the heavens and all that is in the earth. And Allah is All-Sufficient as a Disposer of affairs.

(209) So, as for those who believed (in the Oneness of Allah - Islamic Monotheism) and did deeds of righteousness, He will give them their (due) rewards - and more out of His Bounty. But as for those who refused His worship and were proud, He will punish them with a painful torment. And they will not find for themselves besides Allah any protector or helper.

(210) So, as for those who believed in Allah and held fast to Him, He will admit them to His Mercy and Grace (i.e. Paradise), and guide them to Himself by the Straight Path.
