The word(s) "devout" appears 12 time(s) in 12 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Guard strictly your (habit of) prayers, especially the Middle Prayer; and stand before Allah in a devout (frame of mind).

(2) Those who show patience, Firmness and self-control; who are true (in word and deed); who worship devoutly; who spend (in the way of Allah); and who pray for forgiveness in the early hours of the morning.

(3) "O Mary! worship Thy Lord devoutly: Prostrate thyself, and bow down (in prayer) with those who bow down."

(4) Men are the protectors and maintainers of women, because Allah has given the one more (strength) than the other, and because they support them from their means. Therefore the righteous women are devoutly obedient, and guard in (the husband's) absence what Allah would have them guard. As to those women on whose part ye fear disloyalty and ill-conduct, admonish them (first), (Next), refuse to share their beds, (And last) beat them (lightly); but if they return to obedience, seek not against them Means (of annoyance): For Allah is Most High, great (above you all).

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

(6) And piety (for all creatures) as from Us, and purity: He was devout,

(7) To Him belongs every being that is in the heavens and on earth: all are devoutly obedient to Him.

(8) But any of you that is devout in the service of Allah and His Messenger, and works righteousness,- to her shall We grant her reward twice: and We have prepared for her a generous Sustenance.

(9) For Muslim men and women,- for believing men and women, for devout men and women, for true men and women, for men and women who are patient and constant, for men and women who humble themselves, for men and women who give in Charity, for men and women who fast (and deny themselves), for men and women who guard their chastity, and for men and women who engage much in Allah's praise,- for them has Allah prepared forgiveness and great reward.

(10) Is one who worships devoutly during the hour of the night prostrating himself or standing (in adoration), who takes heed of the Hereafter, and who places his hope in the Mercy of his Lord - (like one who does not)? Say: "Are those equal, those who know and those who do not know? It is those who are endued with understanding that receive admonition.
