﴿ يَٰٓأَهْلَ ٱلْكِتَٰبِ لِمَ تَكْفُرُونَ بِـَٔايَٰتِ ٱللَّهِ وَأَنتُمْ تَشْهَدُونَ ﴾

“O followers of earlier revelation! Why do you deny the truth of God's messages to which you yourselves bear witness?”

(O People of the Scripture! Why disbelieve you in the revelations of Allah) Muhammad and the Qur'an, (when you (yourselves) bear witness (to the Truth)?) you know from your Scripture that Muhammad is a prophet sent by Allah.
