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 And most of them We found not (true) to their covenant, but most of them We found indeed Fasiqun (rebellious, disobedient to Allah). 102 Then, after them, We sent Moses with our tokens unto Pharaoh and his chiefs, but they repelled them. Now, see the nature of the consequence for the corrupters! 103 Moses said, "Pharaoh, I am a messenger from the Lord of the Universe, 104 duty-bound to say nothing about God but the truth, and I have brought you a clear sign from your Lord. Let the Children of Israel go with me." 105 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew out his hand, and behold! it was white to all beholders! 108
