Their Messengers came to them with clear proofs, yet they would not believe what they had belied before; as such Allah seals the hearts of the unbelievers. 101 And We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient. 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 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 [Pharaoh] said, "If you come with a sign, then produce it, if you are telling the truth." 106 He threw down his staff, and it was clearly a serpent. 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
