Has it not, then, become plain to those who have inherited the earth in the wake of the former generations that, had We so willed, We could have afflicted them for their sins, (they, however, are heedless to basic facts and so) We seal their hearts so that they hear nothing. 100 Those cities - We relate to you, [O Muhammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 101 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 104 And it behoves me to say nothing about Allah except what is true. I have come to you with a clear sign of having been sent from your Lord. So let the Children of Israel go with me.' 105 He answered: 'If you have come with a sign, show it to us if you are of the truthful' 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
