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 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 all Being, 104 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me. 105 Said Firaun, “If you have come with a sign, then present it if you are truthful!” 106 Then Moses threw down his staff and suddenly, unmistakably, it appeared as a serpent, 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
