Sahih Muslim, Tamim Ad Dari's story.
“Narrated Fatimah bint Qays, sister of ad-Dahhak ibn Qays:
Amir ibn Sharahil ash-Sha'bi said: Fatimah bint Qays was among the first emigrant women. I
asked her to narrate to me a Hadith which she had heard directly from Allah's Apostle (peace
be upon him) and there was no extra link between them. She said: Very well, if you like, I am
prepared to do that. He said to her: Well, do so and narrate it to me. She said: … So I set out
towards the mosque and observed prayer with the Allah's Apostle (peace be upon him) and I
was in the row of the women which was near the row of men. When Allah’s Apostle (peace be
upon him) had finished his prayer, he sat on the pulpit, smiling, and said: Every worshipper
should remain sitting in his place. He then said: Do you know why I have asked you to
assemble? They said: Allah and His apostle know best. He said: By Allah, I have not made you
assemble for exhortation or for a warning. I have detained you here because 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 with thirty men of
Banu Lakhm and Banu 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 rowing boat and landed on that island. There was a beast with long thick hair (and
because of this) they could not distinguish his face from his back. They said: Woe to you, who
can you be? Thereupon it said: I am al-Jassasah. They said: What is al-Jassasah? 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 hurried on till we came to that monastery and found a well-built person there with his
hands tied to his neck and iron shackles gripping his legs by the ankle. We said: Woe to you,
who are you? He said: You soon come to know about me, but tell me who you are. We said:
We are people from Arabia and we embarked upon a boat but the waves had been driving us
for one month and they brought us near this island. We took to the rowing boats and landed on
this island. Here a beast with profusely thick hair met us 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-Jassasah. We said: What is al-Jassasah? 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 Baysan. We said: In which respect do you seek information about it? He said: I ask you
whether these trees bear fruit or not. We said: Yes. Thereupon he said: I think these will not
bear fruit. He said: Inform me about the lake of Tabariyyah? We said: What do you want to
know about it? He said: Is there water in it? They said: There is an abundance of water in it.
Thereupon he said: I think it will soon dry up. He again said: Inform me about the spring of
Zughar. They said: What do you want to know about it? He (the chained person) said: Is there
water in it and does it irrigate (the land)? We said to him: Yes, there is an abundance of water
in it and the inhabitants (of Medina) irrigate (land) with its help. He said: Inform me about the
unlettered Prophet; what has he done? We said: He has left Mecca and has settled in Yathrib
(Medina). He said: Do the Arabs fight against him? We said: Yes. He said: How does 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: Had it actually happened? We said:
Yes. Thereupon he said: If it is so, that is better for them that they show obedience to him. I am
going to tell you about myself. I am the Dajjal and will be soon permitted to leave. So I shall
leave and travel in the land, and shall not spare any town where I shall not land within forty
nights except Mecca and Tauba (i.e., Medina). These two (places) are prohibited (areas) for me
and I shall not attempt to enter either of them. An angel with a sword in his hand will confront
me and bar my way and there will be angels to guard every road leading to it. Then Allah's
apostle (peace be upon him) striking the pulpit with the help of the end of his staff said: This
implies Tayba 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 (Fatimah bint Qays) said: I preserved it in my mind (this narration from
Allah's Messenger (peace be upon him).
(Sahih Muslim)
The wars will not be fighting Ya'juj Ma'juj, as no one could beat them said Rasulullah 'alaihi Shalawatullahi wa Salaam, according Hadits related to Bukhari and Muslim, Muslim will subdue the Arabian continents, then Rome, India and Iran.
