Surah Ibrahim — Ayah 33 (14:33)
وَسَخَّرَ لَكُمُ ٱلشَّمۡسَ وَٱلۡقَمَرَ دَآئِبَيۡنِۖ وَسَخَّرَ لَكُمُ ٱلَّيۡلَ وَٱلنَّهَارَ ٣٣
English translation (Saheeh International)
And He subjected for you the sun and the moon, continuous [in orbit], and subjected for you the night and the day.
Brief commentary
Allah subjugated the sun and the moon to continuously orbit. He subjugated the day and the night to alternate, the night for your sleep and rest and the day for your activity and work.
