وَهُوَ ٱلَّذِى خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ فِى سِتَّةِ أَيَّامٍۢ وَكَانَ عَرْشُهُۥ عَلَى ٱلْمَآءِ لِيَبْلُوَكُمْ أَيُّكُمْ أَحْسَنُ عَمَلًۭا ۗ وَلَئِن قُلْتَ إِنَّكُم مَّبْعُوثُونَ مِنۢ بَعْدِ ٱلْمَوْتِ لَيَقُولَنَّ ٱلَّذِينَ كَفَرُوٓا۟ إِنْ هَٰذَآ إِلَّا سِحْرٌۭ مُّبِينٌۭ
And He it is Who created the heavens and the earth in six Days - and His Throne was upon the water - that He might try you, which of you is best in conduct. Yet if thou (O Muhammad) sayest: Lo! ye will be raised again after death! those who disbelieve will surely say: This is naught but mere magic.
Surah Hud(11:7)
