Hadith 2930 Part A

'Umar b. Khattab went along with Allah's Messenger (ﷺ) in the company of some persons to Ibn Sayyad that he found him playing with children near the battlement of Bani Maghala and Ibn Sayyad was at that time just at the threshold of adolescence and he did not perceive (the presence of Holy Prophet) until Allah's Messenger (ﷺ) struck his back with his hands. Allah's Messenger (ﷺ) said : Ibn Sayyad , don't you bear witness that I am the messenger of Allah ? Ibn Sayyad looked toward him and he said : I bear witness to the fact that you the messenger of the unlettered. Ibn Sayyad said to the Allah's Messenger (ﷺ) : Do you bear witness to the fact that I am the messenger of Allah ? Allah's Messenger (ﷺ) rejected this and said : I affirm my faith in Allah and in His messengers. Then Allah's Messenger (ﷺ) said to him : What do you see ? Ibn Sayyad said : It is a Dukh. Thereupon Allah's Messenger (ﷺ) said : May you be disgraced and dishonoured , you would not not be able to go beyond your rank. 'Umar b. Khattab said : Allah's Messenger , permit me that I should strike his neck. Thereupon Allah's Messenger (ﷺ) said : If he is the same (Dajjal) who would appear near the Last Hour , you would not be able to overpower him , and if he is not that there is no good for you to kill him.
