Is it not plain to those who inherit the earth after its inhabitants that if We willed We could smite them for their sins and set a seal upon their hearts, so that 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 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 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 told the Pharaoh, "I am a Messengers from the Lord of the Universe. 104 "I am duty bound to speak nothing of God but the truth I have brought from your Lord a clear sign; so let the people of Israel depart with me." 105 He said: "If you have brought a sign then display it, if what you say is true." 106 So he threw his rod, then lo! it was a clear serpent. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
