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 We have told you the stories of those towns: their messengers came to them with clear signs, but they were never going to believe in something they had already rejected. Thus God seals up the hearts of those who deny the truth. 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 Moosa said, “O Firaun! Indeed I am a Noble Messenger from the Lord Of The Creation.” 104 “It is obligatory for me not to speak concerning Allah except the truth; I have come to you all with a clear sign from your Lord, therefore let the Descendants of Israel go with me.” 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew out his hand, and behold! it was white to all beholders! 108
