Is it not a lesson for the successors of the past generations that had We wanted, We could have punished them for their sins, sealed their hearts and deprived them of hearing? 100 These were the (earlier) habitations whose accounts We have given to you. Their apostles came with clear proofs, but they did not believe what they once denied. That is how God seals the hearts of those who do not believe. 101 We found no (loyalty to any) covenant in most of them. Nay, most of them We found wrong-doers. 102 Then, after them, We sent Moses with our tokens unto Pharaoh and his chiefs, but they repelled them. Now, see the nature of the consequence for the corrupters! 103 And Moosa said, “O Firaun! Indeed I am a Noble Messenger from the Lord Of The Creation.” 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 (Pharaoh) said: "If indeed thou hast come with a Sign, show it forth,- if thou tellest the truth." 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 And he drew out his hand; thereupon it was white [with radiance] for the observers. 108
