And seal up their hearts so that they would not be able to lend an ear to words of guidance? 100 Those cities - We relate to you, [O Muhammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 101 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 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 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
