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
And Pharaoh said: O chiefs! I know not that ye have a god other than me, so kindle for me (a fire), O Haman, to bake the mud; and set up for me a lofty tower in order that I may survey the god of Moses; and lo! I deem him of the liars.
