Surah Al-An'am (The Cattle), Verse 20

اَلَّذِیْنَ اٰتَیْنٰهُمُ الْكِتٰبَ یَعْرِفُوْنَهٗ كَمَا یَعْرِفُوْنَ اَبْنَآءَهُمْ اَلَّذِیْنَ خَسِرُوْۤا اَنْفُسَهُمْ فَهُمْ لَا یُؤْمِنُوْنَ 

Allazeena aatainaa humul Kitaaba ya'rifoonahoo kamaa ya'rifoona abnaaa'ahum; allazeena khasirooo anfusahum fahum laa yu'minoon

“Those to whom We have given the Book know this as they know their own sons. Those who have lost their own souls refuse therefore to believe.”
