فَلَمَّآ أَلۡقَوۡاْ قَالَ مُوسَىٰ مَا جِئۡتُم بِهِ ٱلسِّحۡرُۖ إِنَّ ٱللَّهَ سَيُبۡطِلُهُۥٓ إِنَّ ٱللَّهَ لَا يُصۡلِحُ عَمَلَ ٱلۡمُفۡسِدِينَ ٨١
And when they had thrown, Moses said, "What you have brought is [only] magic. Indeed, Allāh will expose its worthlessness. Indeed, Allāh does not amend the work of corrupters.
Translation: Saheeh International (English)
Each word's meaning and sound
When they threw down their magical spells, Moses (peace be upon him) said to them: What you have shown is magic. Allah will cause what you have done to be nothing and of no effect. You cause corruption on earth by means of your magic and Allah does not set right the action of a person who causes corruption.
