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

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

(12) Those who believe, and do deeds of righteousness, and establish regular prayers and regular charity, will have their reward with their Lord: on them shall be no fear, nor shall they grieve.

(13) There did Zakariya pray to his Lord, saying: "O my Lord! Grant unto me from Thee a progeny that is pure: for Thou art He that heareth prayer!

(14) While he was standing in prayer in the chamber, the angels called unto him: "Allah doth give thee glad tidings of Yahya, witnessing the truth of a Word from Allah, and (be besides) noble, chaste, and a prophet,- of the (goodly) company of the righteous."

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

(16) O ye who believe! Approach not prayers with a mind befogged, until ye can understand all that ye say,- nor in a state of ceremonial impurity (Except when travelling on the road), until after washing your whole body. If ye are ill, or on a journey, or one of you cometh from offices of nature, or ye have been in contact with women, and ye find no water, then take for yourselves clean sand or earth, and rub therewith your faces and hands. For Allah doth blot out sins and forgive again and again.

(17) Hast thou not turned Thy vision to those who were told to hold back their hands (from fight) but establish regular prayers and spend in regular charity? When (at length) the order for fighting was issued to them, behold! a section of them feared men as - or even more than - they should have feared Allah: They said: "Our Lord! Why hast Thou ordered us to fight? Wouldst Thou not Grant us respite to our (natural) term, near (enough)?" Say: "Short is the enjoyment of this world: the Hereafter is the best for those who do right: Never will ye be dealt with unjustly in the very least!

(18) When ye travel through the earth, there is no blame on you if ye shorten your prayers, for fear the Unbelievers May attack you: For the Unbelievers are unto you open enemies.

(19) When thou (O Messenger) art with them, and standest to lead them in prayer, Let one party of them stand up (in prayer) with thee, Taking their arms with them: When they finish their prostrations, let them Take their position in the rear. And let the other party come up which hath not yet prayed - and let them pray with thee, Taking all precaution, and bearing arms: the Unbelievers wish, if ye were negligent of your arms and your baggage, to assault you in a single rush. But there is no blame on you if ye put away your arms because of the inconvenience of rain or because ye are ill; but take (every) precaution for yourselves. For the Unbelievers Allah hath prepared a humiliating punishment.

(20) When ye pass (Congregational) prayers, celebrate Allah's praises, standing, sitting down, or lying down on your sides; but when ye are free from danger, set up Regular prayers: For such prayers are enjoined on believers at stated times.
