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 Those townships! We recount unto thee some tidings thereof. Assuredly there came unto them their apostles with evidences, but they were not such as to believe that which they had erst belied. Thus doth Allah put a seal upon the hearts of the infidels. 101 We found most of them untrue to their covenants, indeed We found most of them to be defiant. 102 So We sent Moses with miracles after (these apostles) to the Pharaoh and his nobles, but they behaved with them high-handedly. See then the end of the authors of evil. 103 Moses said: "O Pharaoh! I am a messenger from the Lord of the worlds,- 104 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 So he cast his staff; and behold, it was a serpent manifest. 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
