And Allah doth know what ye conceal, and what ye reveal. Those whom they invoke besides Allah create nothing and are themselves created. (They are things) dead, lifeless: nor do they know when they will be raised up. Your God is One God. as to those who believe not in the Hereafter, their hearts refuse to know, and they are arrogant. Undoubtedly Allah doth know what they conceal, and what they reveal: verily He loveth not the arrogant. When it is said to them, "What is it that your Lord has revealed?" they say, "Tales of the ancients!" That they may, on the Day of Judgment, their own burdens in full, and also (something) of the burdens of those without knowledge, whom they misled. Alas, how grievous the burdens they will bear!
