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 We did not find in most of them any (faithfulness to) covenant, and We found most of them to be certainly transgressors. 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 Moosa said, “O Firaun! Indeed I am a Noble Messenger from the Lord Of The Creation.” 104 "I am duty bound to speak nothing of God but the truth I have brought from your Lord a clear sign; so let the people of Israel depart with me." 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 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
