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 Such were the townships. We relate some tidings of them unto thee (Muhammad). Their messengers verily came unto them with clear proofs (of Allah's Sovereignty), but they could not believe because they had before denied. Thus doth Allah print upon the hearts of disbelievers (that they hear not). 101 And most of them We found not (true) to their covenant, but most of them We found indeed Fasiqun (rebellious, disobedient to Allah). 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 Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 “It is obligatory for me not to speak concerning Allah except the truth; I have come to you all with a clear sign from your Lord, therefore let the Descendants of Israel go with me.” 105 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew out his hand, and behold! it was white to all beholders! 108
