And We have put a seal upon their hearts, so that they hearken not. 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 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 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 Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 so constituted that I cannot say anything about God but the truth. I have now come unto you with a clear evidence from your Sustainer: let, then, the children of Israel go with me!" 105 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
