Does it not guide the people who inherit the land from former people that We can punish them for their sins if We will? And seal up their hearts so that they would not be able to lend an ear to words of guidance? 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 most of them We found not (true) to their covenant, but most of them We found indeed Fasiqun (rebellious, disobedient to Allah). 102 Then We sent after them Moses with Our signs to Pharaoh and his establishment, but they were unjust toward them. So see how was the end of the corrupters. 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 Then he flung down his staff and lo! it was a serpent manifest; 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
