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 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 many of them faithful to their promises, and found many of them disobedient. 102 Then We sent, after them, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 duty-bound to say nothing about God but the truth, and I have brought you a clear sign from your Lord. Let the Children of Israel go with me." 105 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 Then he drew out his hand, and it appeared luminous to all beholders. 108
