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 (Muhammad), such were the stories of the people who lived in (different) towns in the past. We had sent Our Messengers to them with (certain) miracles but the people still did not believe in what they had rejected before. Such is how God seals the hearts of the unbelievers. 101 We did not find many of them faithful to their promises, and found many of them disobedient. 102 Then after them We sent Musa (Moses) with Our Signs to Fir'aun (Pharaoh) and his chiefs, but they wrongfully rejected them. So see how was the end of the Mufsidun (mischief-makers, corrupts, etc.). 103 Moses said: O Pharaoh! Lo! 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 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 He threw down his staff, and it was clearly a serpent. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
