The word(s) "up" appears 528 time(s) in 470 verse(s) in Quran in Mohsin Khan translation.

(301) And they ask you to hasten on the torment (for them): and had it not been for a term appointed, the torment would certainly have come to them. And surely, it will come upon them suddenly while they perceive not!

(302) Do they not travel in the land, and see what was the end of those before them? They were superior to them in strength, and they tilled the earth and populated it in greater numbers than these (pagans) have done: and there came to them their Messengers with clear proofs. Surely, Allah wronged them not, but they used to wrong themselves.

(303) So glorify Allah [above all that (evil) they associate with Him (O believers)] when you come up to the evening [i.e. offer the (Maghrib ) sunset and ('Isha') night prayers], and when you enter the morning [i.e. offer the (Fajr) morning prayer].

(304) And His are all the praises and thanks in the heavens and the earth; and (glorify Him) in the afternoon (i.e. offer 'Asr prayer) and when you come up to the time, when the day begins to decline (i.e. offer Zuhr prayer). (Ibn 'Abbas said: "These are the five compulsory congregational prayers mentioned in the Qur'an)." [Tafsir At-Tabari]

(305) Of those who split up their religion (i.e. who left the true Islamic Monotheism), and became sects, [i.e. they invented new things in the religion (Bid'ah ), and followed their vain desires], each sect rejoicing in that which is with it.

(306) So set you (O Muhammad صلى الله عليه وسلم) your face (in obedience to Allah, your Lord) to the straight and right religion (Islamic Monotheism), before there comes from Allah a Day which none can avert. On that Day men shall be divided [(in two groups), a group in Paradise and a group in Hell].

(307) And indeed We did send Messengers before you (O Muhammad صلى الله عليه وسلم) to their own peoples. They came to them with clear proofs, then, We took vengeance on those who committed crimes (disbelief, setting partners in worship with Allah, sins); and (as for) the believers, it was incumbent upon Us to help (them).

(308) And verily before that (rain) - just before it was sent down upon them - they were in despair!

(309) And if We send a wind [which would spoil the green growth (tilth) brought up by the previous rain], and they see (their tilth) turn yellow - behold, they then (after their being glad,) would become unthankful (to their Lord Allah as) disbelievers. [Tafsir At-Tabari]

(310) So on that Day no excuse of theirs will avail those who did wrong (by associating partners in worship with Allah, and by denying the Day of Resurrection), nor will they be allowed (then) to return to seek Allah's Pleasure (by having Islamic Faith with righteous deeds and by giving up polytheism, sins and crimes with repentance).
