Surah Ar-Ra'd
وَيَقُولُ ٱلَّذِينَ كَفَرُوا۟ لَسْتَ مُرْسَلًا ۚ قُلْ كَفَىٰ بِٱللَّهِ شَهِيدًۢا بَيْنِى وَبَيْنَكُمْ وَمَنْ عِندَهُۥ عِلْمُ ٱلْكِتَـٰبِ
Wa yaqūlul-lażīna kafarū lasta mursalā(n), qul kafā billāhi syahīdam bainī wa bainakum, wa man ‘indahū ‘ilmul-kitāb(i).
And those who have disbelieved say, "You are not a messenger." Say, [O Muhammad], "Sufficient is Allah as Witness between me and you, and [the witness of] whoever has knowledge of the Scripture."
