Or did not those who inherited the land after its owners, get enough guidance that if We will, We can afflict them with calamity for their sins? And We set seals upon 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 no covenant in most of them; and most of them We found 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! I am a Messenger from the Lord of the universe. 104 duty-bound to say nothing about God but the truth, and I have brought you a clear sign from your Lord. Let the Children of Israel go with me." 105 Said he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 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
