Is it not a guidance to those who inherit the earth after those who inhabited it that, did We will, We would smite them because of their sins, sealing 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 most of them not true to their words; and indeed We found most of them disobedient. 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 am a messenger from the Lord of 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 he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
