Pharaoh's tyranny and arrogance

قَالَ فِرْعَوْنُ ءَامَنتُم بِهِۦ قَبْلَ أَنْ ءَاذَنَ لَكُمْ ۖ إِنَّ هَـٰذَا لَمَكْرٌ 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.

فَلَمَّا جَآءَهُم بِٱلْحَقِّ مِنْ عِندِنَا قَالُوا۟ ٱقْتُلُوٓا۟ أَبْنَآءَ ٱلَّذِينَ ءَامَنُوا۟ مَعَهُۥ وَٱسْتَحْيُوا۟ نِسَآءَهُمْ ۚ وَمَا كَيْدُ ٱلْكَـٰفِرِينَ إِلَّا فِى ضَلَـٰلٍ

And when he brought them the truth from Us, they said, "Kill the sons of those who have believed with him and keep their women alive." But the plan of the disbelievers is not except in error.
