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 We have told you the stories of those towns: their messengers came to them with clear signs, but they were never going to believe in something they had already rejected. Thus God seals up the hearts of those who deny the truth. 101 We found no (loyalty to any) covenant in most of them. Nay, most of them We found wrong-doers. 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 Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 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 putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
