Ar-Ra'd · 13:43

43. Those who disbelieved in Allah say: You, O Muhammad, have not been sent by Allah. Tell them, O Messenger, Allah is sufficient as a witness between me and you to the fact that I have been sent from my Lord to you, as well as those who have knowledge of the heavenly scriptures that contain my description. The one for whom Allah is a witness to His truthfulness, is not harmed by the rejection of those who deny him.
