Translation for 6:20

ٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَعۡرِفُونَهُۥ كَمَا يَعۡرِفُونَ أَبۡنَآءَهُمُۘ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ فَهُمۡ لَا يُؤۡمِنُونَ ٢٠
Those to whom We gave the Scripture recognize him ˹to be a true prophet˺ as they recognize their own children. Those who have ruined themselves will never believe.
