Do not the people who inherited the earth from the (earlier) inhabitants perceive that We could afflict them too for their sins if We pleased, and put seals on their hearts that they may not hear (the voice of truth)? 100 These towns-- We relate to you some of their stories, and certainly their apostles came to them with clear arguments, but they would not believe in what they rejected at first; thus does Allah set a seal over the hearts of the unbelievers 101 And We did not find in most of them any (faithfulness to) covenant, and We found most of them to be certainly transgressors. 102 Then we raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers. 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me. 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, when lo: it was white unto the beholders. 108
