Thus it is that Allah seals the hearts of those who deny the truth. 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, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise 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 Said Firaun, “If you have come with a sign, then present it if you are truthful!” 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand, and lo, it was white to the beholders. 108
