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 These were the (earlier) habitations whose accounts We have given to you. Their apostles came with clear proofs, but they did not believe what they once denied. That is how God seals the hearts of those who do not believe. 101 And We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient. 102 Then We sent, after them, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 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 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me. 105 [Fir'aun (Pharaoh)] said: "If you have come with a sign, show it forth, - if you are one of those who tell the truth." 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 Then he drew out his hand and it was luminous to the onlookers. 108
