On entering the island...
On entering the island, they encountered a hirsute hairy mount, whose forepart could not be distinguished from the backside, when they said: Woe to you, what are you? It said: I am al-Jassasah. Then it advised them to look at a man inside the convent, pointing to him. On going into the convent, they met the greatest man in nature, and firmest in fetters, with his hands tied together to his neck, between his knees up to the heels, with iron chains.
When he recognized them to be among the Arabs, he layed before them numerous questions, for which they gave answers. Then he said to them: Tell me what has the Prophet of illiterate done? They said: He departed Mecca and settled down in Yathrib. He asked: Have the Arabs fought him? They replied: Yea. He said: What has he done to them? They told him that he had overcome whoever came close to him from among the Arabs, and they obeyed him. He said: I apprise you about myself.
I am Jesus (Messias) and I am about 341 to be permitted to rise out, when I will go out... I will proceed on earth for forty days, through which I shall enter every and each village I pass by, other than Mecca and Tibah as they are both forbidden for me. Whenever I intended to enter any of them, I will be received by an angel holding in his hand an unsheathed sword to restrain me from (entering) it.
After stating this, he thrusted the messenger with his wand, on the pulpit saying: This is Tibah, this is Tibah, this is Tibah, meaning al-Madinah. Abu Hurayrah never missed this report without foisting it with a breath of his oddities. So he narrated that between the two horns of al-Jassasah there was a distance of one parasang for the rider!
I came across a comment on this hadith by al-Allamah al-Sayyid Rashid Rida (may God's mercy be upon him), as follows: About hadith of Jassasah which is related by Tamim al-Dari to the Messenger of Allah and recorded by Muslim in his Sahih through chains contradicting each other in respect of its text, it can be said that this difference in the text was caused by some narrators mentioned in the Sahih, and it can't be taken as caused by multiplicity of story.
342 Further, can the narration of Tamim al Dari to the Messenger — if its chain be free from defects — make the hadith supplementary to what the Prophet (S) uttered of his own accord, so as to determine the veracity of its origin in accordance with his (S) permission or approval of an act, as indicated by his warrant and permission?
