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 These are the dwellings – the affairs of which We relate to you (Prophet Mohammed – peace and blessings be upon him); and indeed their (respective) Noble Messengers came to them with clear proofs; so they were not able to believe in what they had denied before; this is how Allah sets seals upon the hearts of disbelievers. 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 after them We sent Moses with Our signs to Pharaoh and his chiefs, but they wrongfully rejected them: So see what was the end of those who made mischief. 103 Moses said: 'Pharaoh, I am a Messenger from the Lord of the Worlds, 104 duty-bound to say nothing about God but the truth, and I have brought you a clear sign from your Lord. Let the Children of Israel go with me." 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
