But We seal over their hearts so they do not hear. 100 To those [earlier] communities - some of whose stories We relate to you - there had indeed come Messengers with clear proofs, but they would not believe what they had once rejected as false. Thus it is that Allah seals the hearts of those who deny the truth. 101 And We did not find in most of them any (faithfulness to) covenant, and We found most of them to be certainly transgressors. 102 Then after them We sent Moses with Our signs to Pharaoh and his chiefs, but they wrongfully rejected them: So see what was the end of those who made mischief. 103 Moses said: 'Pharaoh, I am a Messenger from the Lord of the Worlds, 104 Incumbent it is upon me that I speak naught respecting Allah save the truth; surely I have brought you an evidence from your Lord; wherefore let then go with me the Children of Isra'il. 105 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 Therefore Moosa put down his staff – it immediately turned into a visible python. 107 And he drew forth his hand, and lo, it was white to the beholders. 108
