The word(s) "prayer" appears 130 time(s) in 90 verse(s) in Quran in Mohsin Khan translation.

(51) Those (Muslim rulers) who, if We give them power in the land, (they) enjoin Iqamat-as-Salat [i.e. to perform the five compulsory congregational Salat (prayers) (the males in mosques)], to pay the Zakat and they enjoin Al-Ma'ruf (i.e. Islamic Monotheism and all that Islam orders one to do), and forbid Al-Munkar (i.e. disbelief, polytheism and all that Islam has forbidden) [i.e. they make the Qur'an as the law of their country in all the spheres of life]. And with Allah rests the end of (all) matters (of creatures).

(52) Those who offer their Salat (prayers) with all solemnity and full submissiveness.

(53) And those who strictly guard their (five compulsory congregational) Salawat (prayers) (at their fixed stated hours).

(54) It is these who hasten in the good deeds, and they are foremost in them [e.g. offering the compulsory Salat (prayers) in their (early) stated, fixed times and so on].

(55) In houses (mosques) which Allah has ordered to be raised (to be cleaned, and to be honoured), in them His Name is remembered [i.e. Adhan, Iqamah, Salat (prayers), invocations, recitation of the Qur'an etc.]. Therein glorify Him (Allah) in the mornings and in the afternoons or the evenings,

(56) See you not (O Muhammad صلى الله عليه وسلم) that Allah, He it is Whom glorify whosoever is in the heavens and the earth, and the birds with wings out-spread (in their flight)?. Of each one He (Allah) knows indeed his Salat (prayer) and his glorification, [or everyone knows his Salat (prayer) and his glorification]; and Allah is All-Aware of what they do.

(57) O you who believe! Let your slaves and slave-girls, and those among you who have not come to the age of puberty ask your permission (before they come to your presence) on three occasions: before Fajr (morning) Salat (prayer), and while you put off your clothes for the noonday (rest), and after the 'Isha' (late-night) Salat (prayer). (These) three times are of privacy for you; other than these times there is no sin on you or on them to move about, attending to each other. Thus Allah makes clear the Ayat (the Verses of this Qur'an, showing proofs for the legal aspects of permission for visits) to you. And Allah is All-Knowing, All-Wise.

(58) Who sees you (O Muhammad صلى الله عليه وسلم) when you stand up (alone at night for Tahajjud prayers).

(59) And your movements among those who fall prostrate (to Allah in the five compulsory congregational prayers).

(60) Recite (O Muhammad صلى الله عليه وسلم) what has been revealed to you of the Book (the Qur'an), and perform As-Salat (Iqamat-as-Salat). Verily, As-Salat (the prayer) prevents from Al-Fahsha' (i.e. great sins of every kind, unlawful sexual intercourse) and Al-Munkar (i.e. disbelief, polytheism, and every kind of evil wicked deed) and the remembering (praising) of (you by) Allah (in front of the angels) is greater indeed [than your remembering (praising) of Allah in prayers. And Allah knows what you do.
