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

(91) If ye invoke them, they will not listen to your call, and if they were to listen, they cannot answer your (prayer). On the Day of Judgment they will reject your "Partnership". and none, (O man!) can tell thee (the Truth) like the One Who is acquainted with all things.

(92) Nor can a bearer of burdens bear another's burdens if one heavily laden should call another to (bear) his load. Not the least portion of it can be carried (by the other). Even though he be nearly related. Thou canst but admonish such as fear their Lord unseen and establish regular prayer. And whoever purifies himself does so for the benefit of his own soul; and the destination (of all) is to Allah.

(93) Those who rehearse the Book of Allah, establish regular prayer, and spend (in Charity) out of what We have provided for them, secretly and openly, hope for a commerce that will never fail:

(94) (In the days of old), Noah cried to Us, and We are the best to hear prayer.

(95) They will say: "Did there not come to you your messengers with Clear Signs?" They will say, "Yes". They will reply, "Then pray (as ye like)! But the prayer of those without Faith is nothing but (futile wandering) in (mazes of) error!"

(96) And your Lord says: "Call on Me; I will answer your (prayer): but those who are too arrogant to serve Me will surely find themselves in Hell - in humiliation!"

(97) When We bestow favours on man, he turns away, and gets himself remote on his side (instead of coming to Us); and when evil seizes him, (he comes) full of prolonged prayer!

(98) Those who hearken to their Lord, and establish regular prayer; who (conduct) their affairs by mutual Consultation; who spend out of what We bestow on them for Sustenance;

(99) Muhammad is the messenger of Allah; and those who are with him are strong against Unbelievers, (but) compassionate amongst each other. Thou wilt see them bow and prostrate themselves (in prayer), seeking Grace from Allah and (His) Good Pleasure. On their faces are their marks, (being) the traces of their prostration. This is their similitude in the Taurat; and their similitude in the Gospel is: like a seed which sends forth its blade, then makes it strong; it then becomes thick, and it stands on its own stem, (filling) the sowers with wonder and delight. As a result, it fills the Unbelievers with rage at them. Allah has promised those among them who believe and do righteous deeds forgiveness, and a great Reward.

(100) Allah has indeed heard (and accepted) the statement of the woman who pleads with thee concerning her husband and carries her complaint (in prayer) to Allah: and Allah (always) hears the arguments between both sides among you: for Allah hears and sees (all things).
