And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 101 We did not find many of them faithful to their promises, and found many of them disobedient. 102 Then We sent, after them, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 103 Moses said, "Pharaoh, I am a messenger from the Lord of the Universe, 104 I must only speak what is true about God. I have brought you miracles from your Lord; therefore, let the children of Israel go free". 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 Then [Musa (Moses)] threw his stick and behold! it was a serpent, manifest! 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
