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

(41) Perform As-Salat (Iqamat-as-Salat) from mid-day till the darkness of the night (i.e. the Zuhr, 'Asr, Maghrib and 'Isha' prayers), and recite the Qur'an in the early dawn (i.e. the morning prayer). Verily, the recitation of the Qur'an in the early dawn is ever witnessed (attended by the angels in charge of mankind of the day and the night) .

(42) And in some parts of the night (also) offer the Salat (prayer) with it (i.e. recite the Qur'an in the prayer), as an additional prayer (Tahajjud optional prayer - Nawafil) for you (O Muhammad صلى الله عليه و سلم). It may be that your Lord will raise you to Maqam Mahmud (a station of praise and glory, i.e. the honour of intercession on the Day of Resurrection.) .

(43) Say (O Muhammad صلى الله عليه و سلم): "Invoke Allah or invoke the Most Gracious (Allah), by whatever name you invoke Him (it is the same), for to Him belong the Best Names. And offer your Salat (prayer) neither aloud nor in a low voice, but follow a way between.

(44) And keep yourself (O Muhammad صلى الله عليه وسلم) patiently with those who call on their Lord (i.e. your companions who remember their Lord with glorification, praising in prayers, and other righteous deeds) morning and afternoon, seeking His Face; and let not your eyes overlook them, desiring the pomp and glitter of the life of the world; and obey not him whose heart We have made heedless of Our Remembrance, and who follows his own lusts, and whose affair (deeds) has been lost.

(45) "And He has made me blessed wheresoever I be, and has enjoined on me Salat (prayer), and Zakat, as long as I live."

(46) And he used to enjoin on his family and his people As-Salat (the prayers) and the Zakat and his Lord was pleased with him.

(47) Then, there has succeeded them a posterity who have given up As-Salat (the prayers) [i.e. made their Salat (prayers) to be lost, either by not offering them or by not offering them perfectly or by not offering them in their proper fixed times] and have followed lusts. So they will be thrown in Hell.

(48) So bear patiently (O Muhammad صلى الله عليه وسلم) what they say, and glorify the praises of your Lord before the rising of the sun, and before its setting, and during some hours of the night, and at the ends of the day (an indication for the five compulsory congregational prayers), that you may become pleased (with the reward which Allah shall give you).

(49) And enjoin As-Salat (the prayer) on your family, and be patient in offering them [i.e. the Salat (prayers)]. We ask not of you a provision (i.e. to give Us something: money): We provide for you. And the good end (i.e. Paradise) is for the Muttaqun (the pious - See V.2:2).

(50) And (remember) when We showed Ibrahim (Abraham) the site of the (Sacred) House (the Ka'bah at Makkah) (saying): "Associate not anything (in worship) with Me, [La ilaha illallah (none has the right to be worshipped but Allah) - Islamic Monotheism], and sanctify My House for those who circumambulate it, and those who stand up (for prayer), and those who bow (submit themselves with humility and obedience to Allah), and make prostration (in prayer);"
