Is it not a guidance to those who inherit the earth after those who inhabited it that, did We will, We would smite them because of their sins, sealing their hearts so they do not hear? 100 Those townships! We recount unto thee some tidings thereof. Assuredly there came unto them their apostles with evidences, but they were not such as to believe that which they had erst belied. Thus doth Allah put a seal upon the hearts of the infidels. 101 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 102 Then We sent, after them, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 103 And Musa said: O Firon! surely I am an apostle from the Lord of the worlds: 104 "Proper it is for me that I say nothing concerning Allah but the truth. Indeed I have come unto you from your Lord with a clear proof. So let the Children of Israel depart along with me." 105 He answered: 'If you have come with a sign, show it to us if you are of the truthful' 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
