Is it not an indication to those who inherit the land after its people (who thus reaped the consequence of evil-doing) that, if We will, We can smite them for their sins and print upon their hearts so that they hear not? 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 We sent after them Moses with Our signs to Pharaoh and his establishment, but they were unjust toward them. So see how was the end of the corrupters. 103 And Moses said, "O Pharaoh, I am a messenger from the Lord of the worlds 104 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So 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 Then he flung down his staff and lo! it was a serpent manifest; 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
