Al-An'am 20

ٱلَّذِينَ ءَاتَيْنَـٰهُمُ ٱلْكِتَـٰبَ يَعْرِفُونَهُۥ كَمَا يَعْرِفُونَ أَبْنَآءَهُمُ ۘ ٱلَّذِينَ خَسِرُوٓا۟ أَنفُسَهُمْ فَهُمْ لَا يُؤْمِنُونَ

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.
