Al-Lu'lu Wal-Marjan 1858 — The Book of Al-Fitn (Trials and Afflictions etc.) and the Portents of the Hour

Abu Sa'id al-Khudri Narrated from:

Allâh’s Messenger صلى الله عليه وسلم told us a long narrative about Ad-Dajjâl, and among the many things he mentioned was his saying, “ Ad-Dajjâl will come and it will be forbidden for him to pass through the entrances of Al-Madîna. He will land in some of the salty barren areas (outside) Al-Madîna; on that day the best man or one of the best men will come up to him and say, ‘I testify that you are the same Dajjâl whose description was given to us by Allâh’s Messenger صلى الله عليه وسلم.’ Ad-Dajjâl will say to the people, ‘If I kill this man and bring him back to life again, will you doubt my claim?’ They will say, ‘No.’ Then Ad-Dajjâl will kill that man and bring him back to life. That man will say, ‘Now I know your reality better than before.’ Ad-Dajjâl will say, ‘I want to kill him but I cannot.’” ( Sahîh Al-Bukhârî, Hadîth No. 106, Vol. 3)
