To those who inherit the earth in succession to its (previous) possessors, is it not a guiding, (lesson) that, if We so willed, We could punish them (too) for their sins, and seal up their hearts so that they could not hear? 100 Unto those [earlier] communities - some of whose stories We [now] relate unto thee - there had indeed come apostles of their own with all evidence of the truth; but they would not believe in anything to which they had once given the lie: thus it is that God seals the hearts of those who deny the truth; 101 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 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! Lo! I am a messenger from the Lord of the Worlds, 104 “It is obligatory for me not to speak concerning Allah except the truth; I have come to you all with a clear sign from your Lord, therefore let the Descendants of Israel go with me.” 105 He said: "If you have brought a sign then display it, if what you say is true." 106 Therefore Moosa put down his staff – it immediately turned into a visible python. 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
