Is it not an indication to those who inherit the land after its people (who thus reaped the consequence of evil-doing) that, if We will, We can smite them for their sins and print upon their hearts so that they hear not? 100 To those [earlier] communities - some of whose stories We relate to you - there had indeed come Messengers with clear proofs, but they would not believe what they had once rejected as false. Thus it is that Allah seals the hearts of those who deny the truth. 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 said: "O Pharaoh, I have been sent by the Lord of all the worlds; 104 One for whom it is right to say nothing but truth about Allah. Now have I come unto you (people), from your Lord, with a clear (Sign): So let the Children of Israel depart along with me." 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 Therefore Moosa put down his staff – it immediately turned into a visible python. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
