What did the Prophet Muhammad (saw) say when he saw Ibn Saiyad?
      Narrated Ibn 'Umar:                          Umar and a group of the companions of the Prophet set out with the      Prophet to Ibn Saiyad. He found him playing with some boys near the      hillocks of Bani Maghala. Ibn Saiyad at that time was nearing his      puberty. He did not notice (the Prophet's presence) till the Prophet      stroked him on the back with his hand and said, "Ibn Saiyad! Do you      testify that I am Allah's Apostle?" Ibn Saiyad looked at him and said,     "I testify that you are the Apostle of the illiterates."     Then Ibn Saiyad asked the Prophet. "Do you testify that I am the      apostle of Allah?" The Prophet said to him, "I believe in Allah and      His Apostles." Then the Prophet said (to Ibn Saiyad). "What do you      see?" Ibn Saiyad replied, "True people and false ones visit me." The      Prophet said, "Your mind is confused as to this matter." The Prophet      added, " I have kept something (in my mind) for you." Ibn Saiyad said,     "It is Ad-Dukh." The Prophet said (to him), "Shame be on you! You      cannot cross your limits." On that 'Umar said, "O Allah's Apostle!      Allow me to chop his head off." The Prophet said, "If he should be him     (i.e. Ad-Dajjal) then you cannot overpower him, and should he not be      him, then you are not going to benefit by murdering him."
