Al-Hajj (The Pilgrimage)

Surah 22 · Verse 61

That is because Allah makes the night to enter into the day and He makes the day to enter into the night and Allah is certainly Hearing, Seeing.

ذَٰلِكَ بِأَنَّ اللَّهَ يُولِجُ اللَّيْلَ فِي النَّهَارِ وَيُولِجُ النَّهَارَ فِي اللَّيْلِ وَأَنَّ اللَّهَ سَمِيعٌ بَصِيرٌ
