Is it not plain to those who inherit the earth after its inhabitants that if We willed We could smite them for their sins and set a seal upon their hearts, so that they do not hear. 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 did not find the covenant upheld by the majority of them, but We found most of them evildoers. 102 So We sent Moses with miracles after (these apostles) to the Pharaoh and his nobles, but they behaved with them high-handedly. See then the end of the authors of evil. 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 Incumbent it is upon me that I speak naught respecting Allah save the truth; surely I have brought you an evidence from your Lord; wherefore let then go with me the Children of Isra'il. 105 (Pharaoh) said: If thou comest with a token, then produce it, if thou art of those who speak the truth. 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
