Is it not a guidance to those who inherit the earth after those who inhabited it that, did We will, We would smite them because of their sins, sealing 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 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 We sent after them Moses with Our signs to Pharaoh and his establishment, but they were unjust toward them. So see how was the end of the corrupters. 103 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 thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 Then Moses threw down his staff and suddenly, unmistakably, it appeared as a serpent, 107 And putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
