We recount unto thee some tidings thereof. Assuredly there came unto them their apostles with evidences, but they were not such as to believe that which they had erst belied. Thus doth Allah put a seal upon the hearts of the infidels. 101 And We found no covenant in most of them; and most of them We found ungodly. 102 Then, after them, We sent Moses with our tokens unto Pharaoh and his chiefs, but they repelled them. Now, see the nature of the consequence for the corrupters! 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 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 [Pharaoh] said, "If you come with a sign, then produce it, if you are telling the truth." 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
