The word(s) "pray" appears 169 time(s) in 149 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) 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."

(52) 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.

(53) 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.

(54) The mosques of Allah shall be visited and maintained by such as believe in Allah and the Last Day, establish regular prayers, and practise regular charity, and fear none (at all) except Allah. It is they who are expected to be on true guidance.

(55) The only reasons why their contributions are not accepted are: that they reject Allah and His Messenger; that they come to prayer without earnestness; and that they offer contributions unwillingly.

(56) The Believers, men and women, are protectors one of another: they enjoin what is just, and forbid what is evil: they observe regular prayers, practise regular charity, and obey Allah and His Messenger. On them will Allah pour His mercy: for Allah is Exalted in power, Wise.

(57) Nor do thou ever pray for any of them that dies, nor stand at his grave; for they rejected Allah and His Messenger, and died in a state of perverse rebellion.

(58) But some of the desert Arabs believe in Allah and the Last Day, and look on their payments as pious gifts bringing them nearer to Allah and obtaining the prayers of the Messenger. Aye, indeed they bring them nearer (to Him): soon will Allah admit them to His Mercy: for Allah is Oft-forgiving, Most Merciful.

(59) Of their goods, take alms, that so thou mightest purify and sanctify them; and pray on their behalf. Verily thy prayers are a source of security for them: And Allah is One Who heareth and knoweth.

(60) Never stand thou forth therein. There is a mosque whose foundation was laid from the first day on piety; it is more worthy of the standing forth (for prayer) therein. In it are men who love to be purified; and Allah loveth those who make themselves pure.
