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

(161) Of Allah, to Whom do belong all things in the heavens and on earth! But alas for the Unbelievers for a terrible penalty (their Unfaith will bring them)!-

(162) Their messengers said to them: "True, we are human like yourselves, but Allah doth grant His grace to such of his servants as He pleases. It is not for us to bring you an authority except as Allah permits. And on Allah let all men of faith put their trust.

(163) Whoever works righteousness, man or woman, and has faith, verily, to him will We give a new Life, a life that is good and pure and We will bestow on such their reward according to the best of their actions.

(164) Any one who, after accepting faith in Allah, utters Unbelief,- except under compulsion, his heart remaining firm in faith - but such as open their breast to Unbelief, on them is Wrath from Allah, and theirs will be a dreadful Penalty.

(165) This because they love the life of this world better than the Hereafter: and Allah will not guide those who reject faith.

(166) But verily thy Lord,- to those who leave their homes after trials and persecutions,- and who thereafter strive and fight for the faith and patiently persevere,- Thy Lord, after all this is oft-forgiving, Most Merciful.

(167) Abraham was indeed a model, devoutly obedient to Allah, (and) true in faith, and he joined not gods with Allah:

(168) So We have taught thee the inspired (Message), "Follow the ways of Abraham the True in faith, and he joined not gods with Allah."

(169) It may be that your Lord may (yet) show Mercy unto you; but if ye revert (to your sins), We shall revert (to Our punishments): And we have made Hell a prison for those who reject (all faith).

(170) Those who do wish for the (things of) the Hereafter, and strive therefor with all due striving, and have faith,- they are the ones whose striving is acceptable (to Allah).
