Does it not guide the people who inherit the land from former people that We can punish them for their sins if We will? And seal up their hearts so that they would not be able to lend an ear to words of guidance? 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 did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient. 102 AND AFTER those [early people] We sent Moses with Our messages unto Pharaoh and his great ones, and they wilfully rejected them: and behold what happened in the end to those spreaders of corruption! 103 Moses said: 'Pharaoh, I am a Messenger from the Lord of the Worlds, 104 And it behoves me to say nothing about Allah except what is true. I have come to you with a clear sign of having been sent from your Lord. So let the Children of Israel go with me.' 105 (Pharaoh) said: "If indeed thou hast come with a Sign, show it forth,- if thou tellest the truth." 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
