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 Those were the towns whose story We relate unto you (O Muhammad SAW). And there came indeed to them their Messengers with clear proofs, but they were not such as to believe in that which they had rejected before. Thus Allah does seal up the hearts of the disbelievers (from each and every kind of religious guidance). 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 Moses with Our signs to Pharaoh and his chiefs, but they wrongfully rejected them: So see what was the end of those who made mischief. 103 And Moses said, "O Pharaoh, I am a messenger from the Lord of the worlds 104 One for whom it is right to say nothing but truth about Allah. Now have I come unto you (people), from your Lord, with a clear (Sign): So let the Children of Israel depart along with me." 105 He said: "If you have brought a sign then display it, if what you say is true." 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
