Ar Ra’d Ayah 43
وَيَقُولُ ٱلَّذِينَ كَفَرُواْ لَسْتَ مُرْسَلاًۚ قُلْ كَفَىٰ بِٱللَّهِ شَهِيدَۢا بَيْنِى وَبَيْنَكُمْ وَمَنْ عِندَهُۥ عِلْمُ ٱلْكِتَـٰبِ ٤٣
The disbelievers say, “You ?Mu?ammad? are no messenger.” Say, ?O Prophet,? “Allah is sufficient as a Witness between me and you, as is whoever has knowledge of the Scripture.”
