But they say, "Why are not signs sent down to him from his Lord?" Say, "The signs are only with Allāh, and I am only a clear warner." And is it not sufficient for them that We revealed to you the Book [i.e., the Qur’ān] which is recited to them? Indeed in that is a mercy and reminder for a people who believe. Say, "Sufficient is Allāh between me and you as Witness. He knows what is in the heavens and earth. And they who have believed in falsehood and disbelieved in Allāh - it is those who are the losers."
