Observe, then, what happened to the mischief-makers. 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me. 105 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 Then Moses threw down his staff and suddenly, unmistakably, it appeared as a serpent, 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
