وَسَخَّرَ لَكُمُ ٱلَّيْلَ وَٱلنَّهَارَ وَٱلشَّمْسَ وَٱلْقَمَرَ ۖ وَٱلنُّجُومُ مُسَخَّرَٰتٌۢ بِأَمْرِهِۦٓ ۗ إِنَّ فِى ذَٰلِكَ لَءَايَٰتٍۢ لِّقَوْمٍۢ يَعْقِلُونَ
And He hath constrained the night and the day and the sun and the moon to be of service unto you, and the stars are made subservient by His command. Lo! herein indeed are portents for people who have sense.
