To those who inherit the earth in succession to its (previous) possessors, is it not a guiding, (lesson) that, if We so willed, We could punish them (too) for their sins, and seal up their hearts so that they could 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 And most of them We found not (true) to their covenant, but most of them We found indeed Fasiqun (rebellious, disobedient to Allah). 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 And Musa (Moses) said: "O Fir'aun (Pharaoh)! I am a Messenger from the Lord of the 'Alamin (mankind, jinns and all that exists). 104 “It is obligatory for me not to speak concerning Allah except the truth; I have come to you all with a clear sign from your Lord, therefore let the Descendants of Israel go with me.” 105 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
