بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ
In the name of Allah, Most Gracious, Most Merciful.
6:20
ٱلَّذِينَ ءَاتَيْنَـٰهُمُ ٱلْكِتَـٰبَ يَعْرِفُونَهُۥ كَمَا يَعْرِفُونَ أَبْنَآءَهُمُ ۘ ٱلَّذِينَ خَسِرُوٓا۟ أَنفُسَهُمْ فَهُمْ لَا يُؤْمِنُونَ
6:20
Those to whom We have given the Scripture (Jews and Christians) recognize him (i.e. Muhammad SAW as a Messenger of Allah, and they also know that there is no Ilah (God) but Allah and Islam is Allah's Religion), as they recognize their own sons. Those who destroy themselves will not believe. (Tafsir At-Tabari) - Muhammad Taqi-ud-Din al-Hilali and Muhammad Muhsin Khan (English)
