Surah Al-An'am, ayah 20

ٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَعۡرِفُونَهُۥ كَمَا يَعۡرِفُونَ أَبۡنَآءَهُمُۘ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ فَهُمۡ لَا يُؤۡمِنُونَ ٢٠

Alladhīna ātaynāhumul-kitāba ya'rifūnahū kamā ya'rifūna abnā'ahumul-ladhīna khasirū anfusahum fahum lā yu'minūn

Those to whom We have given the Scripture recognize it²⁹⁹ as they recognize their [own] sons. Those who will lose themselves [in the Hereafter] do not believe.
