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

(31) And this is a Book which We have sent down, bringing blessings, and confirming (the revelations) which came before it: that thou mayest warn the mother of cities and all around her. Those who believe in the Hereafter believe in this (Book), and they are constant in guarding their prayers.

(32) Say: "Truly, my prayer and my service of sacrifice, my life and my death, are (all) for Allah, the Cherisher of the Worlds:

(33) Say: "My Lord hath commanded justice; and that ye set your whole selves (to Him) at every time and place of prayer, and call upon Him, making your devotion sincere as in His sight: such as He created you in the beginning, so shall ye return."

(34) O Children of Adam! wear your beautiful apparel at every time and place of prayer: eat and drink: But waste not by excess, for Allah loveth not the wasters.

(35) As to those who hold fast by the Book and establish regular prayer,- never shall We suffer the reward of the righteous to perish.

(36) Verily those whom ye call upon besides Allah are servants like unto you: Call upon them, and let them listen to your prayer, if ye are (indeed) truthful!

(37) Who establish regular prayers and spend (freely) out of the gifts We have given them for sustenance:

(38) Their prayer at the House (of Allah) is nothing but whistling and clapping of hands: (Its only answer can be), "Taste ye the penalty because ye blasphemed."

(39) But when the forbidden months are past, then fight and slay the Pagans wherever ye find them, an seize them, beleaguer them, and lie in wait for them in every stratagem (of war); but if they repent, and establish regular prayers and practise regular charity, then open the way for them: for Allah is Oft-forgiving, Most Merciful.

(40) But (even so), if they repent, establish regular prayers, and practise regular charity,- they are your brethren in Faith: (thus) do We explain the Signs in detail, for those who understand.
