Surah Al-An'am, Verse 20

ٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَعۡرِفُونَهُۥ كَمَا يَعۡرِفُونَ أَبۡنَآءَهُمُۘ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ فَهُمۡ لَا يُؤۡمِنُونَ٢٠

alladhīna ātaynāhumu l-kitāba yaʿrifūnahu kamā yaʿrifūna abnāahumu alladhīna khasirū anfusahum fahum lā yu'minūna

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