Dajjal is Alive Right Now

We know that Dajjal (a.k.a. the False Messiah) is alive right now and that he is imprisoned in a remote island somewhere.  This proof for this is the hadith narrated below:

Rasoolullah (SAW) once gathered the Muslims in the masjid and said: “I have kept you here because Tamim ad-Dari, a Christian man who has embraced Islam, told me something which agrees with what I have told you about the Dajjal. He told me that he had sailed in a ship with thirty men from Banu Lakham and Banu Judham. The waves tossed them about for a month, then they came near an island at sunset. They approached the island on the ship’s rafts, and landed. They were met by a beast that was so hairy that they could not tell its front from its back.
They said: ‘Woe to you! What are you?’
It said: ‘I am al-Jassasah.’ They said: ‘What is al-Jassasah?’
It said: ‘O people, go to this man in the monastery, for he is very eager to know about you.’
Tamim said that when it named a person to us we were afraid lest it be a devil. Tamim said, ‘We quickly went to the monastery. There we found a huge man with his hands tied up to his neck and with iron shackles between his legs up to the ankles.
We said: ‘Woe to you, who are you?’
It said: ‘You will soon know about me. Tell me who you are.’
We said: ‘We are people from Arabia. We sailed on a ship, but the waves have been tossing us about for a month, and they brought us to your island, where we met a beast which was so hairy that we could not tell its front from its back.
We said to it: ‘Woe to you what are you?’ She said: ‘I am al-Jassasah.’ We asked: ‘What is al-Jassasah?’ and it told us: ‘Go to this man in the monastery, for he is very eager to know about you.’ So we came to you quickly, fearing that it might be a devil.’
The man said: ‘Tell me about the date-palms of Beisan.’
We said: ‘What do you want to know about them’?’
He said: ‘I want to know whether these trees bear fruits or not.’
We said ‘Yes’.
He said: ‘Soon they will not bear fruits.’ Then he said: ‘Tell me about the lake of Tabariyah (in Palestine).’
We said: ‘What do you want to know about it?’
He said: ‘Is there water in it’?’
We said: ‘There is plenty of water in it.’
He said: ‘Soon it will become dry.’ Then he said: ‘Tell me about the spring of Zughar.’
We asked: ‘What do you want to know about it’?’
He asked: ‘Is there water in it, and does it irrigate the land’?’
We said: ‘Yes, there is plenty of water in it, and the people use it to irrigate the land.’
Then he said: ‘Tell me about the illiterate Prophet [Muhammad], what has he done?’
We said: ‘He has left Makkah and settled in Yathrib (later Madinah).’
He said: ‘Do the Arabs fight against him’?’
We said ‘Yes’.
He said: ‘How does he deal with them?’
So we told him that Rasoolullah (SAW) had overcome the Arabs around him and that they had followed him.
He asked: ‘Has it really happened?’
We said yes.
He said: ‘It is better for them that they follow him. Now I will tell you about myself. I am the Dajjal. I will soon be permitted to leave this place: I will emerge and travel about the Earth. In forty nights, I will pass through every town, except Makkah and Madinah, for these have been forbidden to me. Every time I try to enter either of them, I will be met by an angel bearing an unsheathed sword, who will prevent me from entering. There will be angels guarding them at every passage leading to them.’”
