Do not the people who inherited the earth from the (earlier) inhabitants perceive that We could afflict them too for their sins if We pleased, and put seals on their hearts that they may not hear (the voice of truth)? 100 (Muhammad), such were the stories of the people who lived in (different) towns in the past. We had sent Our Messengers to them with (certain) miracles but the people still did not believe in what they had rejected before. Such is how God seals the hearts of the unbelievers. 101 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 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 [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 [Pharaoh] said, "If you come with a sign, then produce it, if you are telling the truth." 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
