29 Preface أَلَم تَرَ أَنَّ اللَّهَ يولِجُ اللَّيلَ فِي النَّهارِ وَيولِجُ النَّهارَ فِي اللَّيلِ وَسَخَّرَ الشَّمسَ وَالقَمَرَ كُلٌّ يَجري إِلىٰ أَجَلٍ مُسَمًّى وَأَنَّ اللَّهَ بِما تَعمَلونَ خَبيرٌAhmed AliDo you not see that God makes the night succeed the day, the day succeed the night? And He has harnessed the sun and the moon so that each runs its appointed course. Surely God is aware of all you do.
