فَلَمَّا أَلْقَواْ قَالَ مُوسَى مَا جِئْتُم بِهِ السِّحْرُ إِنَّ اللّهَ سَيُبْطِلُهُ إِنَّ اللّهَ لاَ يُصْلِحُ عَمَلَ الْمُفْسِدِينَ
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.
When they had had their throw, Moses said: "What ye have brought is sorcery: Allah will surely make it of no effect: for Allah prospereth not the work of those who make mischief.
And when they had cast, Moses said: That which ye have brought is magic. Lo! Allah will make it vain. Lo! Allah upholdeth not the work of mischief-makers.
