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 These towns-- We relate to you some of their stories, and certainly their apostles came to them with clear arguments, but they would not believe in what they rejected at first; thus does Allah set a seal over the hearts of the unbelievers 101 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 102 After those We sent forth Moses with Our signs to Pharaoh and his nobles, but they dealt with Our signs unjustly. Observe, then, what happened to the mischief-makers. 103 Moses said, "Pharaoh, I am a messenger from the Lord of the Universe, 104 worthy to say nothing regarding God except the truth. I have brought a clear sign to you from your Lord; so send forth with me the Children of Israel.' 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
