To those who inherit the earth in succession to its (previous) possessors, is it not a guiding, (lesson) that, if We so willed, We could punish them (too) for their sins, and seal up their hearts so that they could not hear? 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 We found no (loyalty to any) covenant in most of them. Nay, most of them We found wrong-doers. 102 After them We sent Moses with Our signs to Pharaoh and his chiefs. But they willfully rejected them. Consider the end of the evil-doers. 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 "Proper it is for me that I say nothing concerning Allah but the truth. Indeed I have come unto you from your Lord with a clear proof. 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 So he threw his rod, then lo! it was a clear serpent. 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
