Has it, then, not become obvious unto those who have inherited the earth in the wake of former generations that, if We so willed, We could smite them [too] by means of their sins, sealing their hearts so that they cannot hear [the truth]? 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 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 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 Musa (Moses) said: "O Fir'aun (Pharaoh)! I am a Messenger from the Lord of the 'Alamin (mankind, jinns and all that exists). 104 And it behoves me to say nothing about Allah except what is true. I have come to you with a clear sign of having been sent from your Lord. So let the Children of Israel go with me.' 105 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand (from his bosom), and lo! it was white for the beholders. 108
