Quran 40:25 from Surah Ghafir on Divine Marvels.
فَلَمَّا جَآءَهُم بِٱلۡحَقِّ مِنۡ عِندِنَا قَالُواْ ٱقۡتُلُوٓاْ أَبۡنَآءَ ٱلَّذِينَ ءَامَنُواْ مَعَهُۥ وَٱسۡتَحۡيُواْ نِسَآءَهُمۡۚ وَمَا كَيۡدُ ٱلۡكَٰفِرِينَ إِلَّا فِي ضَلَٰلٖ
English translation: Then when he brought to them the truth from Us they said Kill (the) sons (of) those who believe with him and let live their women And not (is the) plot (of) the disbelievers but in error
Transliteration: falamma jaahum bil-haqi min indina qalu uq'tulu abnaa alladhina amanu ma'ahu wa-is'tahyu nisaahum wama kaydu al-kafirina illa fi dalalin
