Quran 6:20 from Surah Al-An'aam on Divine Marvels.
ٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَعۡرِفُونَهُۥ كَمَا يَعۡرِفُونَ أَبۡنَآءَهُمُۘ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ فَهُمۡ لَا يُؤۡمِنُونَ
English translation: Those (to) whom We have given them the Book they recognize him as they recognize their sons Those who lost themselves then they (do) not believe
Transliteration: alladhina ataynahumu al-kitaba ya'rifunahu kama ya'rifuna abnaahumu alladhina khasiru anfusahum fahum la yu'minuna
