فَلَمَّآ أَلْقَوْا۟ قَالَ مُوسَىٰ مَا جِئْتُم بِهِ ٱلسِّحْرُ ۖ إِنَّ ٱللَّهَ سَيُبْطِلُهُۥٓ ۖ إِنَّ ٱللَّهَ لَا يُصْلِحُ عَمَلَ ٱلْمُفْسِدِينَ

So when they cast down, Musa said to them: What you have brought is deception; surely Allah will make it naught; surely Allah does not make the work of mischief-makers to thrive.
