Or did not those who inherited the land after its owners, get enough guidance that if We will, We can afflict them with calamity for their sins? And We set seals upon their hearts so they do 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 did not find most of them true to their covenants; indeed We found most of them to be transgressors. 102 After those We sent forth Moses with Our signs to Pharaoh and his nobles, but they dealt with Our signs unjustly. Observe, then, what happened to the mischief-makers. 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 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 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 Then he flung down his staff and lo! it was a serpent manifest; 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
