When they commit evil acts, they say, "We found our fathers doing such, and God ordered us to it." Say, "God does not order evil! Do you say about God what you do not know?"

[7:28] In Euthyphro, Plato narrates a conversation between Socrates and a pious priest on the meaning of virtue and the baffling question, "is it right because God says so or does God says so because it is right?" We know from the Quran that Truth or Justice are among God's attributes and thus their existence is the essence of God's self. In other words, the answer to the Socratic question should be "both are true: it is right because God says so and God says so because it is right." See 37:105-107.
