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 did not find most of them true to their covenants; indeed We found most of them to be transgressors. 102 Then after them We sent Moses with Our signs to Pharaoh and his chiefs, but they wrongfully rejected them: So see what was the end of those who made mischief. 103 Moses said: 'Pharaoh, I am a Messenger from the Lord of the Worlds, 104 "I am duty bound to speak nothing of God but the truth I have brought from your Lord a clear sign; so let the people of Israel depart with me." 105 (Pharaoh) said: "If indeed thou hast come with a Sign, show it forth,- if thou tellest the truth." 106 So he threw his rod, then lo! it was a clear serpent. 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
