وَيَقُولُ الَّذِينَ كَفَرُوا لَسْتَ مُرْسَلًا ۚ قُلْ كَفَىٰ بِاللَّهِ شَهِيدًا بَيْنِي وَبَيْنَكُمْ وَمَنْ عِنْدَهُ عِلْمُ الْكِتَابِ

Va yakoolullazeena kafaroo lasta mursalea(mursalan), kul kafea billeahi shaheedan baynee va baynakum va man indahu ilmul kiteab(kiteabi).

And those who disbelieve say: “You have not been sent as a Messenger”. Say: “Sufficient as a Witness between me and you is Allah and those too who have the knowledge of the Book.”
