Surah Al-An'am — Ayah 20 (6:20)
ٱلَّذِينَ ءَاتَيۡنَٰهُمُ ٱلۡكِتَٰبَ يَعۡرِفُونَهُۥ كَمَا يَعۡرِفُونَ أَبۡنَآءَهُمُۘ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ فَهُمۡ لَا يُؤۡمِنُونَ ٢٠
English translation (Saheeh International)
Those to whom We have given the Scripture recognize it1 as they recognize their [own] sons. Those who will lose themselves [in the Hereafter] do not believe.
- - The Qur’ān. Also interpreted as "him," meaning Muḥammad (ﷺ).
Brief commentary
The Jews who were given the Torah and the Christians who were given the Gospel recognise the Prophet Muhammad (peace be upon him) completely, just as they recognise their own children from other children. They are the ones who have lost their own souls by making them enter the fire of Hell, and they will not believe.
