The Creator and Controller of this World is Allah Allah tells:ذَلِكَ بِأَنَّ اللَّهَ يُولِجُ اللَّيْلَ فِي النَّهَارِ وَيُولِجُ النَّهَارَ فِي اللَّيْلِThat is because Allah merges the night into the day, and He merges the day into the night.Allah tells us that He is the Creator Who directs the affairs of His creation as He wills.He tells us:قُلِ اللَّهُمَّ مَـلِكَ الْمُلْكِ تُوْتِى الْمُلْكَ مَن تَشَأءُ وَتَنزِعُ الْمُلْكَ مِمَّن تَشَأءُ وَتُعِزُّ مَن تَشَأءُ وَتُذِلُّ مَن تَشَأءُ بِيَدِكَ الْخَيْرُ إِنَّكَ عَلَى كُلِّ شَىْءٍ قَدِيرٌتُولِجُ الَّيْلَ فِى الْنَّهَارِ وَتُولِجُ النَّهَارَ فِى الَّيْلِ وَتُخْرِجُ الْحَىَّ مِنَ الْمَيِّتِ وَتُخْرِجُ الَمَيِّتَ مِنَ الْحَىِّ وَتَرْزُقُ مَن تَشَأءُ بِغَيْرِ حِسَابٍSay:"O Allah!

Verily, You are able to do all things. You make the night to enter into the day, and You make the day to enter into the night, You bring the living out of the dead, and You bring the dead out of the living. And You give wealth and sustenance to whom You will, without limit. (3:26-27)The meaning of "merging" the night into the day and the day into the night is that the one encroaches upon the other, and vice versa.
