Do not the people who inherited the earth from the (earlier) inhabitants perceive that We could afflict them too for their sins if We pleased, and put seals on their hearts that they may not hear (the voice of truth)? 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 We found no covenant in the most part of them; indeed, We found the most part of them 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 And Moses said: "O Pharaoh! Verily, I am an apostle from the Sustainer of all the worlds, 104 "I am duty bound to speak nothing of God but the truth I have brought from your Lord a clear sign; so let the people of Israel depart with me." 105 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 Then he drew out his hand, and it appeared luminous to all beholders. 108
