﴿ يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ ۚ وَهُوَ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ ﴾

“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].”

He makes the night pass into He makes it enter the day so that it increases while the night diminishes and makes the day pass into the night so that it increases while the day diminishes. And He is Knower of what is in the breasts of what it contains of secrets and convictions.
