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 And We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient. 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 incumbent upon me is that I say nothing of Allah except the truth. I bring you a clear proof from your Lord. So let the Children of Israel depart with me' 105 (Pharaoh) said: "If indeed thou hast come with a Sign, show it forth,- if thou tellest the truth." 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
