And seal up their hearts so that they would not be able to lend an ear to words of guidance? 100 Those townships! 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 Most of them We found not men (true) to their covenant: but most of them We found rebellious and 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 said, 'Pharaoh, I am a Messenger from the Lord of all Being, 104 "Proper it is for me that I say nothing concerning Allah but the truth. Indeed I have come unto you from your Lord with a clear proof. So let the Children of Israel depart along with me." 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
