Narrated Ibn `Umar: `Umar set out along with the Prophet (p.b.u.h) with a group of people to Ibn Saiyad till they saw him playing with the boys near the hillocks of Bani Mughala. Ibn Saiyad at that time was nearing his puberty and did not notice (us) until the Prophet stroked him with his hand and said to him, “Do you testify that I am Allah’s Apostle?” Ibn Saiyad looked at him and said, “I testify that you are the Messenger of illiterates.” Then Ibn Saiyad asked the Prophet (p.b.u.h), “Do you testify that I am Allah’s Apostle?” The Prophet (p.b.u.h) refuted it and said, “I believe in Allah and His Apostles.” Then he said (to Ibn Saiyad), “What do you think?” Ibn Saiyad answered, “True people and liars visit me.” The Prophet said, “You have been confused as to this matter.” Then the Prophet said to him, “I have kept something (in my mind) for you, (can you tell me that?)” Ibn Saiyad said, “It is Al−Dukh (the smoke).” (2) The Prophet said, “Let you be in Ignominy. You cannot cross your limits.” On that `Umar, said, “O Allah’s Apostle! Allow me to chop his head off.” The Prophet (p.b.u.h) said, “If he is he (i.e. Dajjal), then you cannot overpower him, and if he is not, then there is no use of murdering him.” (Ibn `Umar added): Later on Allah’s Apostle (p.b.u.h) once again went along with Ubai bin Ka`b to the date−palm trees (garden) where Ibn Saiyad was staying. The Prophet (p.b.u.h) wanted to hear something from Ibn Saiyad before Ibn Saiyad could see him, and the Prophet (p.b.u.h) saw him lying covered with a sheet and from where his murmurs were heard. Ibn Saiyad’s mother saw Allah’s Apostle while he was hiding himself behind the trunks of the date−palm trees. She addressed Ibn Saiyad, “O Saf ! (and this was the name of Ibn Saiyad) Here is Muhammad.” And with that Ibn Saiyad got up. The Prophet said, “Had this woman left him (Had she not disturbed him), then Ibn Saiyad would have revealed the reality of his case.

‘Abdullah b. Umar reported: ‘Umar b. Khattab went along with Allah’s Messenger (may peace be upon him) in the company of some persons toIbn Sayyad that he found him playing with children near the bettlement of Bani Maghala and Ibn Sayyad was at that time just at the threshold of adolescence and he did not perceive (the presence of Holy Prophet) until Allah’s Messenger (may peace be upon him) struck his back with his hands. Allah’s Messenger (may peace be upon him) said: Ibn Sayyad, don’t you bear witness that I am the messenger of Allah? Ibn Sayyad looked toward him and he said: I bear witness to the fact that you the messenger of the unlettered. Ibn Sayyad said to the Allah’s Messenger (may peace be upon him): Do you bear witness to the fact that I am the messenger of Allah? Allah’s Messenger (may peace be upon him) rejected this and said: I affirm my faith in Allah and in His messengers. Then Allah’s Messenger (may peace be upon him) said to him: What do you see? Ibn Sayyad said: It us a Dukh. Thereupon Allah’s Messenger (may peace be upon him) said: May you be disgraced and dishonored, you would not not be able to go beyond your rank. ‘Umar b. Khattab said: Allah’s Messenger, permit me that I should strike his neck. Therupon Allah’s Messenger (may peace be upon him) said: If he is the same (Dajjal) who would appear near the Last Hour, you would not be able to overpower him, and he is not that ther is no good for you to kill him. ‘Abdullah b. ‘Umar further narrated that after some time Allah’s Messenger (may peace be upon him) and Ubayy b. Ka’b went towards the palm trees where Ibn Sayyad was. When Allah’s Messenger (may peace be upon him) went near the tree he hid himself behind a tree with the intention of hearing something from Ibn sayyad before Ibn Sayyad could see him, but Allah’s Messenger (may peace be upon him) saw him on a bed with a blanket around him from which a murmuring sound was being heard and Ibn Sayyad’s mother saw Allah’s Messenger (may peace be upon him) behind the trunk of the palm tree. She said to Ibn Sayyad: Saf (that being his name), here is Muhammad. Thereupon Ibn Sayyad jumped up murmuring and Allah’s Messenger (may peace be upon him) said: If she had left him alone he would have made things clear. Abdullah b. Umar told that Allah’s Messenger (may peace be upon him) stood up amongst the people and lauded Allah as He deserved, then he made a mention of the Dajjal and said: I warn you of him and there is no Prophet who has not warned his people against the Dajjal. Even Noah warned (against him) but I am going to tell you a thing which no Prophet told his people. You must know that he (the Dajjal) is one−eyed and Allah, the Exalted and Glorious, is not one−eyed. Ibn Shihab said: ‘Umar b. Thabit al−Ansari informed me that some of the Companions of Allah’s Messenger (may peace be upon him) informed him that the day when Allah’s Messenger (may peace be upon him) warned people against the Dajjal, he also said: There would be written between his two eyes (the word) Kafir (infidel) and everyone who would resent his deeds would be able to read or every Muslim would be about to read, and he also said: Bear this thing in mind that none amongst you would be able to see Allah, the Exalted and Glorious, until he dies.

“….When Allah’s Messenger (may peace be upon him) had finished his prayer, he sat on the pulpit smiling and said: Every worshiper 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, forTamim
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 (spy). 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 &aid: 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 (Sea of Galilee)? 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 him? We informed him that he had overcome those in his neighborhood 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 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 (may peace be upon him) 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 As 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 (may peace be upon him)….”
