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

(531) They (the angels) said: "We have been sent to a people who are Mujrimun (criminals, disbelievers, polytheists, sinners).

(532) Surely! Therein is indeed a sign for the believers.

(533) Look not with your eyes ambitiously at what We have bestowed on certain classes of them (the disbelievers), nor grieve over them. And lower your wings for the believers (be courteous to the fellow-believers).

(534) Who have made the Qur'an into parts. (i.e. believed in one part and disbelieved in the other). [Tafsir At-Tabari]

(535) Therefore proclaim openly (Allah's Message - Islamic Monotheism) that which you are commanded, and turn away from Al-Mushrikun (polytheists, idolaters, and disbelievers - See V.2:105).

(536) The Event (the Hour or the punishment of disbelievers and polytheists or the Islamic laws or commandments) ordained by Allah will come to pass, so seek not to hasten it. Glorified and Exalted be He above all that they associate as partners with Him.

(537) Your Ilah (God) is One Ilah (God - Allah, none has the right to be worshipped but He). But for those who believe not in the Hereafter, their hearts deny (the faith in the Oneness of Allah), and they are proud.

(538) Then, on the Day of Resurrection, He will disgrace them and will say: "Where are My (so called) partners concerning whom you used to disagree and dispute (with the believers, by defying and disobeying Allah)?" Those who have been given the knowledge (about the Torment of Allah for the disbelievers) will say: "Verily! Disgrace and misery this Day are upon the disbelievers.

(539) Do they (the disbelievers and polytheists) await but that the angels should come to them [to take away their souls (at death)], or there should come the command (i.e. the torment or the Day of Resurrection) of your Lord? Thus did those before them. And Allah wronged them not, but they used to wrong themselves.

(540) In order that He may make manifest to them the truth of that wherein they differ, and that those who disbelieved (in Resurrection, and in the Oneness of Allah) may know that they were liars.
