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 These are the dwellings – the affairs of which We relate to you (Prophet Mohammed – peace and blessings be upon him); and indeed their (respective) Noble Messengers came to them with clear proofs; so they were not able to believe in what they had denied before; this is how Allah sets seals upon the hearts of disbelievers. 101 We did not find many of them faithful to their promises, and found many of them disobedient. 102 Then we raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers. 103 And Musa said: O Firon! surely 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 He said: "If you have brought a sign then display it, if what you say is true." 106 Then [Musa (Moses)] threw his stick and behold! it was a serpent, manifest! 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
