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 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 after them, We sent Moosa with our signs to Firaun and his court members, but they did injustice to those signs; therefore see what sort of fate befell the mischievous! 103 And Moses said, "O Pharaoh, I am a messenger 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 Firaun, “If you have come with a sign, then present it if you are truthful!” 106 Therefore Moosa put down his staff – it immediately turned into a visible python. 107 And putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
