Or did not those who inherited the land after its owners, get enough guidance that if We will, We can afflict them with calamity for their sins? And We set seals upon their hearts so they do not hear. 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 and in most of them We found no [inner] bond with anything that is right - and most of them We found to be iniquitous indeed. 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! Verily, I am an apostle from the Sustainer of all the worlds, 104 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 He answered: 'If you have come with a sign, show it to us if you are of the truthful' 106 He threw down his staff, and it was clearly a serpent. 107 And he drew forth his hand (from his bosom), and lo! it was white for the beholders. 108
