Quran 52:48 — Mt. Sinai (Al-Toor)

You shall steadfastly persevere in carrying out your Lord's command—you are in our eyes—and glorify and praise your Lord when you get up.

[52:47] Those who transgress suffer retribution here, but most of them do not know.

[52:49] Also during the night glorify Him, and at dawn as the stars fade away.
