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 and in most of them We found no [inner] bond with anything that is right - and most of them We found to be iniquitous indeed. 102 So We sent Moses with miracles after (these apostles) to the Pharaoh and his nobles, but they behaved with them high-handedly. See then the end of the authors of evil. 103 And Moses said: "O Pharaoh! Verily, I am an apostle from the Sustainer of all the worlds, 104 duty-bound to say nothing about God but the truth, and I have brought you a clear sign from your Lord. Let the Children of Israel go with me." 105 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
