Guideth it not those who inherit the land after the people thereof, that, had We willed, We would have afflicted them for their sins? And We have put a seal upon their hearts, so that they hearken not. 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 We found no covenant in most of them; and most of them We found ungodly. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 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 thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
