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 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 found no covenant in the most part of them; indeed, We found the most part of them ungodly. 102 Then after them We sent Moses with Our signs to Pharaoh and his chiefs, but they wrongfully rejected them: So see what was the end of those who made mischief. 103 Moses told the Pharaoh, "I am a Messengers from the Lord of the Universe. 104 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 He threw down his staff, and it was clearly a serpent. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
