And We seal up their hearts so that they hear not? 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 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 102 AND AFTER those [early people] We sent Moses with Our messages unto Pharaoh and his great ones, and they wilfully rejected them: and behold what happened in the end to those spreaders of corruption! 103 Moses said: "O Pharaoh, I have been sent by the Lord of all 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 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
