وَيَقُولُ ٱلَّذِينَ كَفَرُواْ لَسۡتَ مُرۡسَلًا ۚ قُلۡ كَفَىٰ بِٱللَّهِ شَهِيدًا بَيۡنِى وَبَيۡنَكُمۡ وَمَنۡ عِندَهُۥ عِلۡمُ ٱلۡكِتَٰبِ
The Unbelievers say: "No messenger art thou." Say: "Enough for a witness between me and you is Allah, and such as have knowledge of the Book."<br/>
And those who disbelieve say, to you: 'You have not been sent [by God]!' Say, to them: 'God suffices as a witness between me and you, to my truthfulness [as a messenger], and he who possesses knowledge of the Book', from among the Christian and Jewish believers.
