The word(s) "believed" appears 189 time(s) in 171 verse(s) in Quran in Mohsin Khan translation.

(91) The parable of those who disbelieved in their Lord is that their works are as ashes, on which the wind blows furiously on a stormy day; they shall not be able to get aught of what they have earned. That is the straying, far away (from the Right Path).

(92) And those who believed (in the Oneness of Allah and His Messengers and whatever they brought) and did righteous deeds, will be made to enter Gardens under which rivers flow, - to dwell therein for ever (i.e. in Paradise), with the Permission of their Lord. Their greeting therein will be: Salam (peace!).

(93) Say (O Muhammad صلى الله عليه و سلم) to 'Ibadi (My slaves) who have believed, that they should perform As-Salat (Iqamat-as-Salat ), and spend in charity out of the sustenance We have given them, secretly and openly, before the coming of a Day on which there will be neither mutual bargaining nor befriending.

(94) How much would those who disbelieved wish that they had been Muslims [those who have submitted themselves to Allah's Will in Islam i.e. Islamic Monotheism - this will be on the Day of Resurrection when they will see the disbelievers going to Hell and the Muslims going to Paradise].

(95) They would not believe in it (the Qur'an); and already the example of (Allah's punishment of) the ancients (who disbelieved) has gone forth.

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

(97) 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.

(98) And (remember) the Day when We shall raise up from each nation a witness (their Messenger), then, those who disbelieved will not be given leave (to put forward excuses), nor will they be allowed (to return to the world) to repent and ask for Allah's Forgiveness (of their sins).

(99) Those who disbelieved and hinder (men) from the Path of Allah, for them We will add torment to the torment because they used to spread corruption [by disobeying Allah themselves, as well as ordering others (mankind) to do so].

(100) Whoever disbelieved in Allah after his belief, except him who is forced thereto and whose heart is at rest with Faith; but such as open their breasts to disbelief, on them is wrath from Allah, and theirs will be a great torment.
