Their Messengers said: "Can there be any doubt about (the Existence, Oneness, and absolute Sovereignty of) God, the Originator of the heavens and the earth? He calls you so that He may forgive you your sins and grant you respite until a term appointed by Him (not destroying you because of your sins)." But they said: "You are but mortals like us; you desire to bar us from what our forefathers used to worship: well, then, bring us some clear authority."
