I accompanied Ibn Sayyad to Mecca and he exclaimed, "What I have encountered from people who assert that I am the dajjal! Have you not heard God's messenger say he will have no children? But I have children. Has he not said that he will be an infidel? But I am a Muslim. Has he not said that he will enter neither Medina nor Mecca? But I have come from Medina and am on my way to Mecca." One of the last things he said to me was, "I swear by God that I know when and where he was born and where he is just now, and I know his father and his mother." He made me feel doubtful, so I said, "Confound you for the rest of the day!" He told that when someone asked him if he would like to be that man he replied, "If it were offered to me I would not object." Muslim transmitted it.
