The word(s) "believe" appears 855 time(s) in 711 verse(s) in Quran in Abdullah Yusuf Ali translation.

(511) Allah and His angels send blessings on the Prophet: O ye that believe! Send ye blessings on him, and salute him with all respect.

(512) Verily Allah has cursed the Unbelievers and prepared for them a Blazing Fire,-

(513) O ye who believe! Be ye not like those who vexed and insulted Moses, but Allah cleared him of the (calumnies) they had uttered: and he was honourable in Allah's sight.

(514) O ye who believe! Fear Allah, and (always) say a word directed to the Right:

(515) (With the result) that Allah has to punish the Hypocrites, men and women, and the Unbelievers, men and women, and Allah turns in Mercy to the believers, men and women: for Allah is Oft-Forgiving, Most Merciful.

(516) The Unbelievers say, "Never to us will come the Hour": Say, "Nay! but most surely, by my Lord, it will come upon you;- by Him Who knows the unseen,- from Whom is not hidden the least little atom in the heavens or on earth: Nor is there anything less than that, or greater, but is in the Record Perspicuous:

(517) That He may reward those who believe and work deeds of righteousness: for such is Forgiveness and a Sustenance Most Generous."

(518) The Unbelievers say (in ridicule): "Shall we point out to you a man that will tell you, when ye are all scattered to pieces in disintegration, that ye shall (then be raised) in a New Creation?

(519) "Has he invented a falsehood against Allah, or has a spirit (seized) him?"- Nay, it is those who believe not in the Hereafter, that are in (real) Penalty, and in farthest error.

(520) And on them did Satan prove true his idea, and they followed him, all but a party that believed.
