Say: "Allah is sufficient between me and you as a witness on my truthfulness that I am His Messenger, and on your belying for me and your returning the truth which I brought from with Allah, He knows what is in the heavens and the earth, for nothing therein is hidden from Him. And those who believed in the falsehood and disbelieved in Allah-along with these clear indications-those they are the losers in the world and the Hereafter."
