The word(s) "devoutly" appears 6 time(s) in 6 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) 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.

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

(3) 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).

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

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

(6) 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.
