٤٣. وَيَقُولُ ٱلَّذِينَ كَفَرُوا۟ لَسْتَ مُرْسَلًا ۚ قُلْ كَفَىٰ بِٱللَّهِ شَهِيدًۢا بَيْنِى وَبَيْنَكُمْ وَمَنْ عِندَهُۥ عِلْمُ ٱلْكِتَـٰبِ
[43] These disbelievers say, “You are not a Messenger of Allah.” Say, “Allah suffices for a witness between me and you, and every such person who has the knowledge of the Book.”62
62That is "Everyone who has the knowledge of the Divinely revealed Books will bear witness to the fact that my teachings are the same that were imparted by the former prophets."
