Or did not those who inherited the land after its owners, get enough guidance that if We will, We can afflict them with calamity for their sins? And We set seals upon their hearts so they do not hear. 100 To those [earlier] communities - some of whose stories We relate to you - there had indeed come Messengers with clear proofs, but they would not believe what they had once rejected as false. Thus it is that Allah seals the hearts of those who deny the truth. 101 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 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 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 He said: "If you have brought a sign then display it, if what you say is true." 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand (from his bosom), and lo! it was white for the beholders. 108
