سُورَةُ الحَدِيدِ
Surah Al-Hadid·57:6
يُولِجُ اللَّيْلَ فِي النَّهَارِ وَيُولِجُ النَّهَارَ فِي اللَّيْلِ ۚ وَهُوَ عَلِيمٌ بِذَاتِ الصُّدُورِ٦
He makes the night grow longer by shortening the day, and makes the day grow longer by shortening the night; and He has full knowledge of what is in the hearts [of men].
