We recount unto thee some tidings thereof. Assuredly there came unto them their apostles with evidences, but they were not such as to believe that which they had erst belied. Thus doth Allah put a seal upon the hearts of the infidels. 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. Behold that wise was the end of the corrupters! 103 And Musa said: O Firon! surely I am an apostle from the Lord of the worlds: 104 "I am duty bound to speak nothing of God but the truth I have brought from your Lord a clear sign; so let the people of Israel depart with me." 105 Said Firaun, “If you have come with a sign, then present it if you are truthful!” 106 So he threw his rod, then lo! it was a clear serpent. 107 And he drew out his hand, and behold! it was white to all beholders! 108
