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 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 And We did not find in most of them any (faithfulness to) covenant, and We found most of them to be certainly transgressors. 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 And Moses said, "O Pharaoh, I am a messenger from the Lord of the worlds 104 One for whom it is right to say nothing but truth about Allah. Now have I come unto you (people), from your Lord, with a clear (Sign): So let the Children of Israel depart along with me." 105 He said: "If you have brought a sign then display it, if what you say is true." 106 Therefore Moosa put down his staff – it immediately turned into a visible python. 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
