To those who inherit the earth in succession to its (previous) possessors, is it not a guiding, (lesson) that, if We so willed, We could punish them (too) for their sins, and seal up their hearts so that they could not hear? 100 Such were the towns whose story We (thus) relate unto thee: There came indeed to them their messengers with clear (signs): But they would not believe what they had rejected before. Thus doth Allah seal up the hearts of those who reject faith. 101 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 102 AND AFTER those [early people] We sent Moses with Our messages unto Pharaoh and his great ones, and they wilfully rejected them: and behold what happened in the end to those spreaders of corruption! 103 Moses said: 'Pharaoh, I am a Messenger from the Lord of the Worlds, 104 so constituted that I cannot say anything about God but the truth. I have now come unto you with a clear evidence from your Sustainer: let, then, the children of Israel go with me!" 105 He answered: 'If you have come with a sign, show it to us if you are of the truthful' 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 And he drew forth his hand, and lo, it was white to the beholders. 108
