The word(s) "fast" appears 74 time(s) in 64 verse(s) in Quran in Muhammad Pickthal translation.

(31) Such as are steadfast and put their trust in Allah.

(32) That which ye have wasteth away, and that which Allah hath remaineth. And verily We shall pay those who are steadfast a recompense in proportion to the best of what they used to do.

(33) Then lo! thy Lord - for those who became fugitives after they had been persecuted, and then fought and were steadfast - lo! thy Lord afterward is (for them) indeed Forgiving, Merciful.

(34) And every man's augury have We fastened to his own neck, and We shall bring forth for him on the Day of Resurrection a book which he will find wide open.

(35) And when they had gone further, he said unto his servant: Bring us our breakfast. Verily we have found fatigue in this our journey.

(36) (And it was said unto his son): O John! Hold fast the Scripture. And we gave him wisdom when a child,

(37) So eat and drink and be consoled. And if thou meetest any mortal, say: Lo! I have vowed a fast unto the Beneficent, and may not speak this day to any mortal.

(38) Lord of the heavens and the earth and all that is between them! Therefor, worship thou Him and be thou steadfast in His service. Knowest thou one that can be named along with Him?

(39) And (mention) Ishmael, and Idris, and Dhu'l-Kifl. All were of the steadfast.

(40) 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!
