The word(s) "pray" appears 151 time(s) in 102 verse(s) in Quran in Mohsin Khan translation.

(1) And seek help in patience and As-Salat (the prayer) and truly it is extremely heavy and hard except for Al-Khashi'un [i.e. the true believers in Allah - those who obey Allah with full submission, fear much from His Punishment, and believe in His Promise (Paradise) and in His Warnings (Hell)].

(2) And who are more unjust than those who forbid that Allah's Name be glorified and mentioned much (i.e. prayers and invocations, etc.) in Allah's Mosques and strive for their ruin? It was not fitting that such should themselves enter them (Allah's Mosques) except in fear. For them there is disgrace in this world, and they will have a great torment in the Hereafter.

(3) And (remember) when We made the House (the Ka'bah at Makkah) a place of resort for mankind and a place of safety. And take you (people) the Maqam (place) of Ibrahim (Abraham) [or the stone on which Ibrahim (Abraham) عليه السلام stood while he was building the Ka'bah] as a place of prayer (for some of your prayers, e.g. two Rak'at after the Tawaf of the Ka'bahat Makkah), and We commanded Ibrahim (Abraham) and Isma'il (Ishmael) that they should purify My House (the Ka'bah at Makkah) for those who are circumambulating it, or staying (I'tikaf), or bowing or prostrating themselves (there, in prayer).

(4) The fools among the people (pagans, hypocrites, and Jews) will say, "What has turned them (Muslims) from their Qiblah [prayer direction (towards Jerusalem)] to which they used to face in prayer." Say, (O Muhammad صلى الله عليه وسلم) "To Allah belong both, east and the west. He guides whom He wills to the Straight Way."

(5) Thus We have made you [true Muslims - real believers of Islamic Monotheism, true followers of Prophet Muhammad صلى الله عليه وسلم and his Sunnah (legal ways)], a just (and the best) nation, that you be witnesses over mankind and the Messenger (Muhammad صلى الله عليه وسلم) be a witness over you. And We made the Qiblah (prayer direction towards Jerusalem) which you used to face, only to test those who followed the Messenger (Muhammad صلى الله عليه وسلم) from those who would turn on their heels (i.e. disobey the Messenger). Indeed it was great (heavy) except for those whom Allah guided. And Allah would never make your faith (prayers) to be lost (i.e. your prayers offered towards Jerusalem). Truly, Allah is full of Kindness, the Most Merciful towards mankind.

(6) Verily! We have seen the turning of your (Muhammad's صلى الله عليه وسلم) face towards the heaven. Surely, We shall turn you to a Qiblah (prayer direction) that shall please you, so turn your face in the direction of Al-Masjid-al-Haram (at Makkah). And wheresoever you people are, turn your faces (in prayer) in that direction. Certainly, the people who were given the Scripture (i.e. Jews and the Christians) know well that, that (your turning towards the direction of the Ka'bah at Makkah in prayers) is the truth from their Lord. And Allah is not unaware of what they do.

(7) And even if you were to bring to the people of the Scripture (Jews and Christians) all the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they would not follow your Qiblah (prayer direction), nor are you going to follow their Qiblah (prayer direction). And they will not follow each other's Qiblah (prayer direction). Verily, if you follow their desires after that which you have received of knowledge (from Allah), then indeed you will be one of the Zalimun (polytheists, wrong-doers).

(8) For every nation there is a direction to which they face (in their prayers). So hasten towards all that is good. Wheresoever you may be, Allah will bring you together (on the Day of Resurrection). Truly, Allah is Able to do all things.

(9) And from wheresoever you start forth (for prayers), turn your face in the direction of Al-Masjid-Al-Haram (at Makkah), that is indeed the truth from your Lord. And Allah is not unaware of what you do.

(10) And from wheresoever you start forth (for prayers), turn your face in the direction of Al-Masjid-Al-Haram (at Makkah), and wheresoever you are, turn your faces towards it (when you pray) so that men may have no argument against you except those of them that are wrong-doers, so fear them not, but fear Me! - And so that I may complete My Blessings on you and that you may be guided.
