Or did not those who inherited the land after its owners, get enough guidance that if We will, We can afflict them with calamity for their sins? And We set seals upon their hearts so they do not hear. 100 Those were the towns whose story We relate unto you (O Muhammad SAW). And there came indeed to them their Messengers with clear proofs, but they were not such as to believe in that which they had rejected before. Thus Allah does seal up the hearts of the disbelievers (from each and every kind of religious guidance). 101 We found most of them untrue to their covenants, indeed We found most of them to be defiant. 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 Firon! surely I am an apostle from the Lord of the worlds: 104 And it behoves me to say nothing about Allah except what is true. I have come to you with a clear sign of having been sent from your Lord. So let the Children of Israel go with me.' 105 Said he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 Then he drew out his hand and it was luminous to the onlookers. 108
