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 (Muhammad), such were the stories of the people who lived in (different) towns in the past. We had sent Our Messengers to them with (certain) miracles but the people still did not believe in what they had rejected before. Such is how God seals the hearts of the unbelievers. 101 And We found no covenant in most of them; and most of them We found ungodly. 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 Moses said: "O Pharaoh, I have been sent by the Lord of all the worlds; 104 worthy to say nothing regarding God except the truth. I have brought a clear sign to you from your Lord; so send forth with me the Children of Israel.' 105 Said Firaun, “If you have come with a sign, then present it if you are truthful!” 106 Therefore Moosa put down his staff – it immediately turned into a visible python. 107 And he drew out his hand; thereupon it was white [with radiance] for the observers. 108
