The word(s) "faith" appears 272 time(s) in 250 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) Say to those who reject faith: "Soon will ye be vanquished and gathered together to Hell,-an evil bed indeed (to lie on)!

(52) Say: "Obey Allah and His Messenger": But if they turn back, Allah loveth not those who reject faith.

(53) Behold! Allah said: "O Jesus! I will take thee and raise thee to Myself and clear thee (of the falsehoods) of those who blaspheme; I will make those who follow thee superior to those who reject faith, to the Day of Resurrection: Then shall ye all return unto me, and I will judge between you of the matters wherein ye dispute.

(54) "As to those who reject faith, I will punish them with terrible agony in this world and in the Hereafter, nor will they have anyone to help."

(55) Abraham was not a Jew nor yet a Christian; but he was true in faith, and bowed his will to Allah's (Which is Islam), and he joined not gods with Allah.

(56) Without doubt, among men, the nearest of kin to Abraham, are those who follow him, as are also this Prophet and those who believe: And Allah is the Protector of those who have faith.

(57) Among the People of the Book are some who, if entrusted with a hoard of gold, will (readily) pay it back; others, who, if entrusted with a single silver coin, will not repay it unless thou constantly stoodest demanding, because, they say, "there is no call on us (to keep faith) with these ignorant (Pagans)." but they tell a lie against Allah, and (well) they know it.

(58) Nay.- Those that keep their plighted faith and act aright,-verily Allah loves those who act aright.

(59) As for those who sell the faith they owe to Allah and their own plighted word for a small price, they shall have no portion in the Hereafter: Nor will Allah (Deign to) speak to them or look at them on the Day of Judgment, nor will He cleans them (of sin): They shall have a grievous penalty.

(60) How shall Allah Guide those who reject faith after they accepted it and bore witness that the Messenger was true and that Clear Signs had come unto them? but Allah guides not a people unjust.
