The word(s) "prayer" appears 102 time(s) in 94 verse(s) in Quran in Muhammad Habib Shakir translation.

(61) But there came after them an evil generation, who neglected prayers and followed and sensual desires, so they win meet perdition,

(62) Surely I am Allah, there is no god but I, therefore serve Me and keep up prayer for My remembrance:

(63) And enjoin prayer on your followers, and steadily adhere to it; We do not ask you for subsistence; We do give you subsistence, and the (good) end is for guarding (against evil).

(64) And We made them Imams who guided (people) by Our command, and We revealed to them the doing of good and the keeping up of prayer and the giving of the alms, and Us (alone) did they serve;

(65) (To) those whose hearts tremble when Allah is mentioned, and those who are patient under that which afflicts them, and those who keep up prayer, and spend (benevolently) out of what We have given them.

(66) Those who, should We establish them in the land, will keep up prayer and pay the poor-rate and enjoin good and forbid evil; and Allah's is the end of affairs.

(67) And strive hard in (the way of) Allah, (such) a striving as is due to Him; He has chosen you and has not laid upon you an hardship in religion; the faith of your father Ibrahim; He named you Muslims before and in this, that the Apostle may be a bearer of witness to you, and you may be bearers of witness to the people; therefore keep up prayer and pay the poor-rate and hold fast by Allah; He is your Guardian; how excellent the Guardian and how excellent the Helper!

(68) Who are humble in their prayers,

(69) And those who keep a guard on their prayers;

(70) Men whom neither merchandise nor selling diverts from the remembrance of Allah and the keeping up of prayer and the giving of poor-rate; they fear a day in which the hearts and eyes shall turn about;
