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 We have told you the stories of those towns: their messengers came to them with clear signs, but they were never going to believe in something they had already rejected. Thus God seals up the hearts of those who deny the truth. 101 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 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 Musa (Moses) said: "O Fir'aun (Pharaoh)! I am a Messenger from the Lord of the 'Alamin (mankind, jinns and all that exists). 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 (Pharaoh) said: If thou comest with a token, then produce it, if thou art of those who speak the truth. 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 And he drew out his hand, and behold! it was white to all beholders! 108
