﴿ إِنَّ فِرْعَوْنَ عَلَا فِى ٱلْأَرْضِ وَجَعَلَ أَهْلَهَا شِيَعًۭا يَسْتَضْعِفُ طَآئِفَةًۭ مِّنْهُمْ يُذَبِّحُ أَبْنَآءَهُمْ وَيَسْتَحْىِۦ نِسَآءَهُمْ ۚ إِنَّهُۥ كَانَ مِنَ ٱلْمُفْسِدِينَ ﴾

“Behold, Pharaoh exalted himself in the land and divided its people into castes. One group of them he deemed utterly low; he would slaughter their sons and spare (only) their women: for, behold, he was one of those who spread corruption [on earth].”
