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 Those cities - We relate to you, [O Muhammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 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 Moses told the Pharaoh, "I am a Messengers from the Lord of the Universe. 104 incumbent upon me is that I say nothing of Allah except the truth. I bring you a clear proof from your Lord. So let the Children of Israel depart with me' 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 He threw down his staff, and it was clearly a serpent. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
