Has it not become clear to those who inherited the earth after its [previous] people that if We willed, We could afflict them for their sins? But We seal over their hearts so they do not hear. 100 Those villages We narrate their news to you. Their Messengers came to them with clear proofs, yet they would not believe what they had belied before; as such Allah seals the hearts of the unbelievers. 101 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 102 After those We sent forth Moses with Our signs to Pharaoh and his assembly, but with it they harmed. Look at the end of the corrupters. 103 And Moses said, "O Pharaoh, I am a messenger from the Lord of the worlds 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 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 Then Moses threw down his staff and suddenly, unmistakably, it appeared as a serpent, 107 Then he drew out his hand and it was luminous to the onlookers. 108
