But We seal over their hearts so they do not hear. 100 Such were the townships. We relate some tidings of them unto thee (Muhammad). Their messengers verily came unto them with clear proofs (of Allah's Sovereignty), but they could not believe because they had before denied. Thus doth Allah print upon the hearts of disbelievers (that they hear not). 101 And We found no covenant in most of them; and most of them We found ungodly. 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 And Moses said: "O Pharaoh! Verily, I am an apostle from the Sustainer of all the worlds, 104 incumbent upon me is that I say nothing of Allah except the truth. I bring you a clear proof from your Lord. So let the Children of Israel depart with me' 105 (Pharaoh) said: If thou comest with a token, then produce it, if thou art of those who speak the truth. 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
