And We set seals upon 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 We found no (loyalty to any) covenant in most of them. Nay, most of them We found wrong-doers. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them.

I am a Messenger 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 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
