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

(21) And they say: We will not put faith in thee till thou cause a spring to gush forth from the earth for us;

(22) Or thou have a house of gold; or thou ascend up into heaven, and even then we will put no faith in thine ascension till thou bring down for us a book that we can read. Say (O Muhammad): My Lord be Glorified! Am I aught save a mortal messenger?

(23) (Pharaoh) said: Ye put faith in him before I give you leave. Lo! he is your chief who taught you magic. Now surely I shall cut off your hands and your feet alternately, and I shall crucify you on the trunks of palm trees, and ye shall know for certain which of us hath sterner and more lasting punishment.

(24) And strive for Allah with the endeavour which is His right. He hath chosen you and hath not laid upon you in religion any hardship; the faith of your father Abraham (is yours). He hath named you Muslims of old time and in this (Scripture), that the messenger may be a witness against you, and that ye may be witnesses against mankind. So establish worship, pay the poor-due, and hold fast to Allah. He is your Protecting friend. A blessed Patron and a blessed Helper!

(25) He is only a man who hath invented a lie about Allah. We are not going to put faith in him.

(26) And they said: Shall we put faith in two mortals like ourselves, and whose folk are servile unto us?

(27) The (faithful) slaves of the Beneficent are they who walk upon the earth modestly, and when the foolish ones address them answer: Peace;

(28) (Pharaoh) said: Ye put your faith in him before I give you leave. Lo! he doubtless is your chief who taught you magic! But verily ye shall come to know. Verily I will cut off your hands and your feet alternately, and verily I will crucify you every one.

(29) Lo! I am a faithful messenger unto you,

(30) They said: Shall we put faith in thee, when the lowest (of the people) follow thee?
