Is it not clear to those who inherit the earth in succession from its (previous) possessors, that had We willed, We would have punished them for their sins. And We seal up their hearts so that they hear 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 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 102 Then we raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers. 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 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 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 Then Moses threw down his staff and suddenly, unmistakably, it appeared as a serpent, 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
