We had sent Our Messengers to them with (certain) miracles but the people still did not believe in what they had rejected before. Such is how God seals the hearts of the unbelievers. 101 We did not find the covenant upheld by the majority of them, but We found most of them evildoers. 102 Then we raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers. 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 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 Said he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 So he threw his rod, then lo! it was a clear serpent. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
