I have came across this other hadith though where a man is shackled in the monastery and another claiming to be Al Jassasa and later on in the hadith it makes clear that the man shackled in this hadith is the Dajjal. Whether it’s the same man as in the hadith you’re referring to I am unsure, Allah knows best.
But here is the hadith I have found anyway:
- The Book of Tribulations and Portents of the Last Hour. Hadith 149
(24) Chapter Al-Jassasah
Sahih Muslim 2942 a
Amir b. Sharahil Sha’bi Sha’b Hamdan reported that he asked Fatima, daughter of Qais and sister of ad-Dahhak b. Qais and she was the first amongst the emigrant women:
Narrate to me a hadith which you had heard directly from Allah’s Messenger (ﷺ) and there is no extra link in between them. She said: Very well, if you like, I am prepared to do that, and he said to her: Well, do It and narrate that to me. She said: I married the son of Mughira and he was a chosen young man of Quraish at that time, but he fell as a martyr in the first Jihad (fighting) on the side of Allah’s Messenger (ﷺ). When I became a widow, 'Abd al-Rahman b. Auf, one amongst the group of the Companions of Allah’s Messenger (ﷺ), sent me the proposal of marriage. Allah’s Messenger (ﷺ) also sent me such a message for his freed slave Usama b. Zaid. And it had been conveyed to me that Allah’s Messenger (ﷺ) had said (about Usama): He who loves me should also love Usama. When Allah’s Messenger (ﷺ) talked to me (about this matter), I said: My affairs are in your hand. You may marry me to anyone whom you like. He said: You better shift now to the house of Umm Sharik, and Umm Sharik was a rich lady from amongst the Ansar. She spent generously for the cause of Allah and entertained guests very hospitably. I said: Well, I will do as you like. He said: Do not do that for Umm Sharik is a woman who is very frequently visited by guests and I do not like that your head may be uncovered or the cloth may be removed from your shank and the strangers may catch sight of them which you abhor. You better shift to the house of your cousin 'Abdullah b. 'Amr b. Umm Maktum and he is a person of the Bani Fihr branch of the Quraish, and he belonged to that tribe (to which Fatima) belonged. So I shifted to that house, and when my period of waiting was over, I heard the voice of an announcer making an announcement that the prayer would be observed in the mosque (where) congregational prayer (is observed). So I set out towards that mosque and observed prayer along with Allah’s Messenger (ﷺ) and I was in the row of the women which was near the row of men. When Allah’s Messenger (ﷺ) had finished his prayer, he sat on the pulpit smiling and said: Every worshipper should keep sitting at his place. He then said: Do you know why I had asked you to assemble? They said: Allah and His Messenger know best. He said: By Allah. I have not made you assemble for exhortation or for a warning, but I have detained you here, for Tamim Dari, a Christian, who came and accepted Islam, told me something, which agrees with what I was telling, you about the Dajjal. He narrated to me that he had sailed in a ship along with thirty men of Bani Lakhm and Bani Judham and had been tossed by waves in the ocean for a month. Then these (waves) took them (near) the land within the ocean (island) at the time of sunset. They sat in a small side-boat and entered that island. There was a beast with long thick hair (and because of these) they could not distinguish his face from his back. They said: Woe to you, who can you be? Thereupon it said: I am al-Jassasa. They said: What is al-Jassasa? And it said: O people, go to this person in the monastery as he is very much eager to know about you. He (the narrator) said: When it named a person for us we were afraid of it lest it should be a devil. Then we hurriedly went on till we came to that monastery and found a well-built person there with his hands tied to his neck and having iron shackles between his two legs up to the ankles. We said: Woe be upon thee, who are you? And he said: You would soon come to know about me. but tell me who are you. We said: We are people from Arabia and we embarked upon a boat but the sea-waves had been driving us for one month and they brought as near this island. We got Into the side-boats and entered this island and here a beast met us with profusely thick hair and because of the thickness of his hair his face could not be distinguished from his back. We said: Woe be to thee, who are you? It said: I am al- Jassasa. We said: What is al-Jassasa? And it said: You go to this very person in the monastery for he is eagerly waiting for you to know about you. So we came to you in hot haste fearing that that might be the Devil. He (that chained person) said: Tell me about the date-palm trees of Baisan. We said: About what aspect of theirs do you seek information? He said: I ask you whether these trees bear fruit or not. We said: yes. Thereupon he said: I think these would not bear fruits. He said: Inform me about the lake of Tabariyya? We said: Which aspect of it do you want to know? He said: Is there water in it? They said: There is abundance of water in it. Thereupon he said: I think it would soon become dry. He again said: Inform me about the spring of Zughar. They said: Which aspect of it you want to know? He (the chained person) said: Is there water in it and does it irrigate (the land)? We said to him: Yes, there is abundance of water in it and the inhabitants (of Medina) irrigate (land) with the help of it, He said: Inform me about the unlettered Prophet; what has he done? We said: He has come out from Mecca and has settled In Yathrib (Medina). He said: Do the Arabs fight against him? We said: Yes. He said: How did he deal with them? We informed him that he had overcome those in his neighbourhood and they had submitted themselves before him. Thereupon he said to us: Has it actually happened? We said: Yes. Thereupon he said: If it is so that is better for them that they should show obedience to him. I am going to tell you about myself and I am Dajjal and would be soon permitted to get out and so I shall get out and travel in the land, and will not spare any town where I would not stay for forty nights except Mecca and Medina as these two (places) are prohibited (areas) for me and I would not make an attempt to enter any one of these two. An angel with a sword in his hand would confront me and would bar my way and there would be angels to guard every passage leading to it; then Allah’s Messenger (ﷺ) striking the pulpit with the help of the end of his staff said: This implies Taiba meaning Medina. Have I not, told you an account (of the Dajjal) like this? 'The people said: Yes, and this account narrated by Tamim Dari was liked by me for it corroborates the account which I gave to you in regard to him (Dajjal) at Medina and Mecca. Behold he (Dajjal) is in the Syrian sea (Mediterranean) or the Yemen sea (Arabian sea). Nay, on the contrary, he is in the east, he is in the east, he is in the east, and he pointed with his hand towards the east. I (Fatima bint Qais) said: I preserved it in my mind (this narration from Allah’s Messenger (ﷺ).
