Guideth it not those who inherit the land after the people thereof, that, had We willed, We would have afflicted them for their sins? And We have put a seal upon their hearts, so that they hearken not. 100 Such were the towns whose story We (thus) relate unto thee: There came indeed to them their messengers with clear (signs): But they would not believe what they had rejected before. Thus doth Allah seal up the hearts of those who reject faith. 101 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 102 After those We sent forth Moses with Our signs to Pharaoh and his nobles, but they dealt with Our signs unjustly. Observe, then, what happened to the mischief-makers. 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 104 I must only speak what is true about God. I have brought you miracles from your Lord; therefore, let the children of Israel go free". 105 He said: "If you have brought a sign then display it, if what you say is true." 106 Then [Musa (Moses)] threw his stick and behold! it was a serpent, manifest! 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
