The word(s) "prayer" appears 124 time(s) in 112 verse(s) in Quran in Abdullah Yusuf Ali translation.

(81) Seest thou not that it is Allah Whose praises all beings in the heavens and on earth do celebrate, and the birds (of the air) with wings outspread? Each one knows its own (mode of) prayer and praise. And Allah knows well all that they do.

(82) So establish regular prayer and give regular Charity; and obey the Messenger; that ye may receive mercy.

(83) O ye who believe! let those whom your right hands possess, and the (children) among you who have not come of age ask your permission (before they come to your presence), on three occasions: before morning prayer; the while ye doff your clothes for the noonday heat; and after the late-night prayer: these are your three times of undress: outside those times it is not wrong for you or for them to move about attending to each other: Thus does Allah make clear the Signs to you: for Allah is full of knowledge and wisdom.

(84) Who seeth thee standing forth (in prayer),

(85) Those who establish regular prayers and give in regular charity, and also have (full) assurance of the hereafter.

(86) Recite what is sent of the Book by inspiration to thee, and establish regular prayer: for prayer restrains from shameful and unjust deeds; and remembrance of Allah is the greatest (thing in life) without doubt. And Allah knows the (deeds) that ye do.

(87) Turn ye back in repentance to Him, and fear Him: establish regular prayers, and be not ye among those who join gods with Allah,-

(88) Those who establish regular prayer, and give regular Charity, and have (in their hearts) the assurance of the Hereafter.

(89) "O my son! establish regular prayer, enjoin what is just, and forbid what is wrong: and bear with patient constancy whatever betide thee; for this is firmness (of purpose) in (the conduct of) affairs.

(90) And stay quietly in your houses, and make not a dazzling display, like that of the former Times of Ignorance; and establish regular prayer, and give regular Charity; and obey Allah and His Messenger. And Allah only wishes to remove all abomination from you, ye members of the Family, and to make you pure and spotless.
