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

(51) And if ye put no faith in me, then let me go.

(52) And in your creation, and all the beasts that He scattereth in the earth, are portents for a folk whose faith is sure.

(53) This is clear indication for mankind, and a guidance and a mercy for a folk whose faith is sure.

(54) He it is Who sent down peace of reassurance into the hearts of the believers that they might add faith unto their faith. Allah's are the hosts of the heavens and the earth, and Allah is ever Knower, Wise -

(55) And know that the messenger of Allah is among you. If he were to obey you in much of the government, ye would surely be in trouble; but Allah hath endeared the faith to you and hath beautified it in your hearts, and hath made disbelief and lewdness and rebellion hateful unto you. Such are they who are the rightly guided.

(56) O ye who believe! Let not a folk deride a folk who may be better than they (are), not let women (deride) women who may be better than they are; neither defame one another, nor insult one another by nicknames. Bad is the name of lewdness after faith. And whoso turneth not in repentance, such are evil-doers.

(57) The wandering Arabs say: We believe. Say (unto them, O Muhammad): Ye believe not, but rather say "We submit," for the faith hath not yet entered into your hearts. Yet, if ye obey Allah and His messenger, He will not withhold from you aught of (the reward of) your deeds. Lo! Allah is Forgiving, Merciful.

(58) They make it a favour unto thee (Muhammad) that they have surrendered (unto Him). Say: Deem not your Surrender a favour unto me; but Allah doth confer a favour on you, inasmuch as He hath led you to the faith, if ye are earnest.

(59) And in the earth are portents for those whose faith is sure.

(60) And they who believe and whose seed follow them in faith, We cause their seed to join them (there), and We deprive them of nought of their (life's) work. Every man is a pledge for that which he hath earned.
