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 Those cities We relate to thee tidings of; their Messengers came to them with the clear signs, but they were not the ones to believe in that they had cried lies before; so God seals the hearts of the unbelievers. 101 And We found no covenant in most of them; and most of them We found ungodly. 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 worthy to say nothing regarding God except the truth. I have brought a clear sign to you from your Lord; so send forth with me the Children of Israel.' 105 Said Firaun, “If you have come with a sign, then present it if you are truthful!” 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
