And there came indeed to them their Messengers with clear proofs, but they were not such as to believe in that which they had rejected before. Thus Allah does seal up the hearts of the disbelievers (from each and every kind of religious guidance). 101 And We found most of them not true to their words; and indeed We found most of them disobedient. 102 Then We sent after them Moses with Our signs to Pharaoh and his establishment, but they were unjust toward them. So see how was the end of the corrupters. 103 Moses told the Pharaoh, "I am a Messengers from the Lord of the Universe. 104 “It is obligatory for me not to speak concerning Allah except the truth; I have come to you all with a clear sign from your Lord, therefore let the Descendants of Israel go with me.” 105 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
