The word(s) "believed" appears 105 time(s) in 99 verse(s) in Quran in Muhammad Habib Shakir translation.

(81) And he who believed said: O my people! follow me, I will guide you to the right course;

(82) And We delivered those who believed and guarded (against evil).

(83) And if We make him taste mercy from Us after distress that has touched him, he would most certainly say: This is of me, and I do not think the hour will come to pass, and if I am sent back to my Lord, I shall have with Him sure good; but We will most certainly inform those who disbelieved of what they did, and We will most certainly make them taste of hard chastisement.

(84) Those who believed in Our communications and were submissive:

(85) Then as to those who believed and did good, their Lord will make them enter into His mercy; that is the manifest achievement.

(86) As to those who disbelieved: What! were not My communications recited to you? But you were proud and you were a guilty people.

(87) Say: Have you considered if it is from Allah, and you disbelieve in it, and a witness from among the children of Israel has borne witness of one like it, so he believed, while you are big with pride; surely Allah does not guide the unjust people.

(88) And on the day when those who disbelieve shall be brought before the fire: Is it not true? They shall say: Aye! by our Lord! He will say: Then taste the punishment, because you disbelieved.

(89) It is they who disbelieved and turned you away from the Sacred Mosque and (turned off) the offering withheld from arriving at its destined place; and were it not for the believing men and the believing women, whom, not having known, you might have trodden down, and thus something hateful might have afflicted you on their account without knowledge-- so that Allah may cause to enter into His mercy whomsoever He pleases; had they been widely separated one from another, We would surely have punished those who disbelieved from among them with a painful punishment.

(90) When those who disbelieved harbored in their hearts (feelings of) disdain, the disdain of (the days of) ignorance, but Allah sent down His tranquillity on His Apostle and on the believers, and made them keep the word of guarding (against evil), and they were entitled to it and worthy of it; and Allah is Cognizant of all things.
