Is it not clear to those who inherit the earth in succession from its (previous) possessors, that had We willed, We would have punished them for their sins. And We seal up their hearts so that they hear not? 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 We did not find many of them faithful to their promises, and found many of them disobedient. 102 Then, after them, We sent Moses with our tokens unto Pharaoh and his chiefs, but they repelled them. Now, see the nature of the consequence for the corrupters! 103 Moses said: O Pharaoh! Lo! I am a messenger from the Lord of the Worlds, 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 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
