7:123
قَالَ فِرْعَوْنُ ءَامَنتُم بِهِۦ قَبْلَ أَنْ ءَاذَنَ لَكُمْ ۖ إِنَّ هَٰذَا لَمَكْرٌۭ مَّكَرْتُمُوهُ فِى ٱلْمَدِينَةِ لِتُخْرِجُوا۟ مِنْهَآ أَهْلَهَا ۖ فَسَوْفَ تَعْلَمُونَ
Said Pharaoh, "You believed in him before I gave you permission. Indeed, this is a conspiracy which you conspired in the city to expel therefrom its people. But you are going to know.

Tafsir
Ibn Kathīr (abridged)
Fir`awn threatens the Magicians after They believed in Musa and Their Response to Him
Allah mentions the threats that the Fir`awn - may Allah curse him - made to the magicians after they believed Musa, peace be upon him, and the deceit and cunning that Fir`awn showed the people. Fir`awn said,
إِنَّ هَـذَا لَمَكْرٌ مَّكَرْتُمُوهُ فِى الْمَدِينَةِ لِتُخْرِجُواْ مِنْهَآ أَهْلَهَا
(Surely, this is a plot which you have plotted in the city to drive out its people,) meaning Fir`awn proclaimed, `Musa's defeating you today was because you plotted with him and agreed to that.' Fir`awn also said,
إِنَّهُ لَكَبِيرُكُمُ الَّذِى عَلَّمَكُمُ السِّحْرَ
(He (Musa) is your chief who has taught you magic.) 20:71 However, Fir`awn and all those who had any sense of reason knew for sure that what Fir`awn said was utterly false. As soon as Musa came from Madyan, he called Fir`awn to Allah and demonstrated tremendous miracles and clear proofs for the Truth that he brought. Fir`awn then sent emissaries to various cities of his kingdom and collected magicians who were scattered throughout Egypt. Fir`awn and his people chose from them, summoned them, and Fir`awn promised them great rewards. These magicians were very eager to prevail over Musa in front of Fir`awn, so that they might become closer to him. Musa neither knew any of them nor saw or met them before. Fir`awn knew that, but he claimed otherwise to deceive the ignorant masses of his kingdom, just as Allah described them,
