To those who inherit the earth in succession to its (previous) possessors, is it not a guiding, (lesson) that, if We so willed, We could punish them (too) for their sins, and seal up their hearts so that they could not hear? 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 So We sent Moses with miracles after (these apostles) to the Pharaoh and his nobles, but they behaved with them high-handedly. See then the end of the authors of evil. 103 Moses said: "O Pharaoh, I have been sent by the Lord of all the worlds; 104 incumbent upon me is that I say nothing of Allah except the truth. I bring you a clear proof from your Lord. So let the Children of Israel depart with me' 105 [Fir'aun (Pharaoh)] said: "If you have come with a sign, show it forth, - if you are one of those who tell the truth." 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
