Is it not clear to those who inherit the earth after its (former) residents that if We please We would afflict them on account of their faults and set a seal on their hearts so they would 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 found no covenant in the most part of them; indeed, We found the most part of them ungodly. 102 After those We sent forth Moses with Our signs to Pharaoh and his nobles, but they dealt with Our signs unjustly. Observe, then, what happened to the mischief-makers. 103 And Musa said: O Firon! surely I am an apostle from the Lord of the worlds: 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 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 Then he flung down his staff and lo! it was a serpent manifest; 107 And putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
