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

(121) [Fir'aun (Pharaoh)] said: "You have believed in him before I give you leave. Surely, he indeed is your chief, who has taught you magic! So verily, you shall come to know. Verily, I will cut off your hands and your feet on opposite sides, and I will crucify you all."

(122) And he had recited it unto them, they would not have believed in it.

(123) And We saved those who believed, and used to fear Allah, and keep their duty to Him.

(124) And when the Word (of torment) is fulfilled against them, We shall bring out from the earth a beast for them, to speak to them because mankind believed not with certainty in Our Ayat (Verses of the Qur'an and Prophet Muhammad صلى الله عليه وسلم).

(125) So We seized him and his hosts, and We threw them all into the sea (and drowned them). So behold (O Muhammad صلى الله عليه وسلم) what was the end of the Zalimun [wrong-doers, polytheists and those who disbelieved in the Oneness of their Lord (Allah), or rejected the advice of His Messenger Musa (Moses) عليه السلام].

(126) But as for him who repented (from polytheism and sins), believed (in the Oneness of Allah, and in His Messenger Muhammad صلى الله عليه وسلم), and did righteous deeds (in the life of this world), then he will be among those who are successful.

(127) So Lut (Lot) believed in him [Ibrahim's (Abraham) Message of Islamic Monotheism]. He [Ibrahim (Abraham)] said: "I will emigrate for the sake of my Lord. Verily, He is the All-Mighty, the All-Wise. "

(128) Then as for those who believed (in the Oneness of Allah - Islamic Monotheism) and did righteous good deeds, such shall be honoured and made to enjoy luxurious life (forever) in a Garden of Delight (Paradise).

(129) And as for those who disbelieved and belied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, Allah's Messengers, Resurrection, etc.), and the Meeting of the Hereafter, such shall be brought forth to the torment (in the Hell-fire).

(130) Being miserly towards you (as regards help and aid in Allah's Cause). Then when fear comes, you will see them looking to you, their eyes revolving like (those of) one over whom hovers death; but when the fear departs, they will smite you with sharp tongues, miserly towards (spending anything in any) good (and only covetous of booty and wealth). Such have not believed. Therefore Allah makes their deeds fruitless and that is ever easy for Allah.
