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 Those villages We narrate their news to you. Their Messengers came to them with clear proofs, yet they would not believe what they had belied before; as such Allah seals the hearts of the unbelievers. 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 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 Moses told the Pharaoh, "I am a Messengers from the Lord of the Universe. 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 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 And he drew forth his hand (from his bosom), and lo! it was white for the beholders. 108
