﴿ وَقَالَ فِرْعَوْنُ يَٰٓأَيُّهَا ٱلْمَلَأُ مَا عَلِمْتُ لَكُم مِّنْ إِلَٰهٍ غَيْرِى فَأَوْقِدْ لِى يَٰهَٰمَٰنُ عَلَى ٱلطِّينِ فَٱجْعَل لِّى صَرْحًۭا لَّعَلِّىٓ أَطَّلِعُ إِلَىٰٓ إِلَٰهِ مُوسَىٰ وَإِنِّى لَأَظُنُّهُۥ مِنَ ٱلْكَٰذِبِينَ ﴾

“Whereupon Pharaoh said: “O you nobles! I did not know that you could have any deity other than myself Well, then, O Haman, kindle me a fire for [baking bricks of] clay, and then build me a lofty tower, that haply I may have a look at the god of Moses although, behold, I am convinced that he is of those who [always] tell lies!””
