Yet he was lying when he said, “Indeed, I think he is a liar,” for he knew full well that Moses was telling the truth. Allah recounts their debate: Moses said to him, “You have certainly come to know, O Pharaoh, that none has sent these signs down but the Lord of the heavens and the earth as clear proofs, and indeed I think you, O Pharaoh, are doomed” (al-Isrāʾ 17:102). Pharaoh offered no rebuttal; he was silent. Such silence, in the setting of open challenge and argument, signifies defeat and the inability to respond.
About him and his people Allah also says, “They rejected them, while their inner-selves were convinced of them, out of wrongdoing and arrogance” (al-Naml 27:14).
