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 And We did not find in most of them any (faithfulness to) covenant, and We found most of them to be certainly transgressors. 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 Incumbent it is upon me that I speak naught respecting Allah save the truth; surely I have brought you an evidence from your Lord; wherefore let then go with me the Children of Isra'il. 105 He said: "If you have brought a sign then display it, if what you say is true." 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 And he drew forth his hand, and lo, it was white to the beholders. 108
