﴿ 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 has created the heavens and the earth in six aeons; and [ever since He has willed to create life,] the throne of His almightiness has rested upon water. [God reminds you of your dependence on Him] in order to test you [and thus to make manifest] which of you is best in conduct. For thus it is: if thou sayest [unto men], "Behold, you shall be raised again after death!" - they who are bent on denying the truth are sure to answer, "This is clearly nothing but an enchanting delusion"”
