Ar-Ra'd 13:43

وَيَقُولُ ٱلَّذِينَ كَفَرُوا۟ لَسْتَ مُرْسَلًا ۚ قُلْ كَفَىٰ بِ ٱللَّهِ 📿 Divine Name Allāh ٱللَّهُ The One True God, The Divine Essence Generate Calligraphy شَهِيدًۢا بَيْنِى وَبَيْنَكُمْ وَمَنْ عِندَهُۥ عِلْمُ ٱلْكِتَـٰبِ

Wayaqūlu alladhīna kafarū lasta mur'salan qul kafā bil-lahi shahīdan baynī wabaynakum waman ʿindahu ʿil'mu l-kitābi

And those who have disbelieved say, "You are not a messenger." Say, [O Muḥammad], "Sufficient is Allāh as Witness between me and you, and [the witness of] whoever has knowledge of the Scripture."¹
