Has it not become clear to those who inherited the earth after its [previous] people that if We willed, We could afflict them for their sins? But We seal over their hearts so they do not hear. 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 And We found most of them not true to their words; and indeed We found most of them disobedient. 102 After the time of those people, We sent Moses with Our miracles to Pharaoh and his people, but they too rejected Our miracles. Consider, how terrible the end of the evil-doers is! 103 And Moses said: "O Pharaoh! Verily, I am an apostle from the Sustainer of all 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 he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 Then he flung down his staff and lo! it was a serpent manifest; 107 Then he drew out his hand and it was luminous to the onlookers. 108
