Does it not guide the people who inherit the land from former people that We can punish them for their sins if We will? And seal up their hearts so that they would not be able to lend an ear to words of guidance? 100 To those [earlier] communities - some of whose stories We relate to you - there had indeed come Messengers with clear proofs, but they would not believe what they had once rejected as false. Thus it is that Allah seals 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, after them, We sent Moses with our tokens unto Pharaoh and his chiefs, but they repelled them. Now, see the nature of the consequence for the corrupters! 103 And Moses said, "O Pharaoh, I am a messenger 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 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 So he threw his rod, then lo! it was a clear serpent. 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
