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 And We found most of them not true to their words; and indeed We found most of them disobedient. 102 Then after them We sent Musa (Moses) with Our Signs to Fir'aun (Pharaoh) and his chiefs, but they wrongfully rejected them. So see how was the end of the Mufsidun (mischief-makers, corrupts, etc.). 103 And Musa (Moses) said: "O Fir'aun (Pharaoh)! I am a Messenger from the Lord of the 'Alamin (mankind, jinns and all that exists). 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 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 Then he flung down his staff and lo! it was a serpent manifest; 107 And he drew forth his hand, and lo, it was white to the beholders. 108
