Is it not a guidance to those who inherit the earth after those who inhabited it that, did We will, We would smite them because of their sins, sealing their hearts so they do not hear? 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 found most of them untrue to their covenants, indeed We found most of them to be defiant. 102 Then after them We sent Musa (Moses) with Our Signs to Fir'aun (Pharaoh) and his chiefs, but they wrongfully rejected them. So see how was the end of the Mufsidun (mischief-makers, corrupts, etc.). 103 Moses said: "O Pharaoh, I have been sent by the Lord of all the worlds; 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 said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
