The word(s) "faith" appears 72 time(s) in 69 verse(s) in Quran in Muhammad Pickthal translation.

(41) Proclaim their real parentage. That will be more equitable in the sight of Allah. And if ye know not their fathers, then (they are) your brethren in the faith, and your clients. And there is no sin for you in the mistakes that ye make unintentionally, but what your hearts purpose (that will be a sin for you). Allah is ever Forgiving, Merciful.

(42) That He may ask the loyal of their loyalty. And He hath prepared a painful doom for the unfaithful.

(43) And when the true believers saw the clans, they said: This is that which Allah and His messenger promised us. Allah and His messenger are true. It did but confirm them in their faith and resignation.

(44) And say: We (now) believe therein. But how can they reach (faith) from afar off,

(45) Who used to say: Art thou in truth of those who put faith (in his words)?

(46) Lo! (on that day) those who disbelieve are informed by proclamation: Verily Allah's abhorrence is more terrible than your abhorrence one of another, when ye were called unto the faith but did refuse.

(47) And a believing man of Pharaoh's family, who hid his faith, said: Would ye kill a man because he saith: My Lord is Allah, and hath brought you clear proofs from your Lord? If he is lying, then his lie is upon him; and if he is truthful, then some of that wherewith he threateneth you will strike you. Lo! Allah guideth not one who is a prodigal, a liar.

(48) But their faith could not avail them when they saw Our doom. This is Allah's law which hath ever taken course for His bondmen. And then the disbelievers will be ruined.

(49) And thus have We inspired in thee (Muhammad) a Spirit of Our command. Thou knewest not what the Scripture was, nor what the faith. But We have made it a light whereby We guide whom We will of Our bondmen. And lo! thou verily dost guide unto a right path,

(50) Saying: Give up to me the slaves of Allah. Lo! I am a faithful messenger unto you.
