The Prophet of Allah ﷺ said, "The Dajjal will come forth, blind in his left eye, which will be covered by a thick membrane. He will heal the one born blind and the leper, and he will revive the dead. He will say to people, 'I am your Lord.' Whoever says to him, 'You are my lord,' has been seduced by his trial. But whoever says, 'My Lord is Allah,' until he dies, is protected from his trial, and no further trial or punishment will come upon him afterwards.He will remain on the earth as long as Allah wills. Then Isa the son of Maryam will come from the direction of the west, affirming the truth of Muhammad and following his religion, and he will kill the Dajjal. After that, the Hour will come."
أن نبي الله ﷺ كان يقول: إن الدجال خارج وهو أعور عين الشمال، عليها ظفرة غليظة، وإنه يبرى الأكمه والأبرص، ويحيي الموتى، ويقول للناس: أنا ربكم، فمن قال: أنت ربي فقد فتن، ومن قال: ربي الله حتى يموت فقد عصم من فتنته، ولا فتنة بعده عليه ولا عذاب، فيلبث في الأرض ما شاء الله، ثم يجيء عيسى ابن مريم من قبل المغرب مصدقا بمحمد وعلى ملته، فيقتل الدجال، ثم إنما هو قيام الساعة.
Ahmad (20151) and Tabarani in al-Kabir (6918) both narrated it from the hadith of Rawh bin Ubada, who said, Saeed bin Abu Aruba told us, from Qatada, from Hasan, from Samura bin Jundab, and he related it. Its isnad is hasan, on account of the discussion surrounding Hasan, who is the well known Imam Basri, for he was a mudallis (one who conceals defects in transmission), and there is disagreement over whether he actually heard from Samura. The correct view, held by the majority of scholars, is that he heard from him without qualification. The discussion of this is elaborated in the Book of Faith.On this subject there is also a report from Thalaba bin Abbad Abdi, one of the people of Basra, who said, "One day I attended a sermon given by Samura bin Jundab, in which he related a hadith from the Messenger of Allah. He said, 'While I and a young man from the Ansar were shooting arrows at two targets of ours in the time of the Messenger of Allah, the sun, when it was at the height of two or three spear lengths in the eye of the observer, turned black until it looked like a tinawma (a dark-leaved tree). One of us said to his companion, "Let's go to the masjid, for by Allah, the state of this sun is surely going to bring about a great event for the Messenger of Allah concerning his nation." So we hurried to the masjid, and there he was, out in the open. The Messenger of Allah arrived just as we did, coming out to the people. He came forward and led us in prayer, standing longer than he had ever stood with us in any prayer, without us hearing his voice. Then he bowed longer than he had ever bowed with us in any prayer, without us hearing his voice. Then he did the same in the second rakat, and the sun's brightness returned to normal while he was sitting in the second rakat.'"Zuhayr said, "I think he said, 'Then he gave the greeting of peace, praised Allah, extolled Him, and testified that he was the servant of Allah and His Messenger. Then he said, "O people, I appeal to you by Allah, if you know that I have fallen short in conveying any part of the messages of my Lord, tell me so, so that I may convey the messages of my Lord as they ought to be conveyed. And if you know that I have conveyed the messages of my Lord, tell me so."'"He said, "Some men stood up and said, 'We testify that you have indeed conveyed the messages of your Lord, given sincere counsel to your nation, and fulfilled what was upon you.'" Then they fell silent.Then he said, "Now then, some men claim that the eclipse of this sun and the eclipse of this moon, and the departure of these stars from their positions, occur because of the death of great men among the people of the earth. They have spoken falsely. Rather, these are signs among the signs of Allah, by which He makes His servants reflect, so that He may see who among them will be moved to repentance. By Allah, ever since I stood to pray, I have seen what you are all going to encounter in the affairs of both your worldly life and your afterlife. And by Allah, the Hour will not come until thirty liars appear, the last of them being the one-eyed Dajjal, whose left eye is disfigured, like the eye of Abu Yahya," referring to an elder of the Ansar at that time, whose dwelling was between there and Ayesha's chamber."When he appears, or however he said it, he will claim that he is Allah. Whoever believes in him, accepts him as true, and follows him will gain no benefit from any righteous deed he had previously done. And whoever disbelieves in him and rejects him will not be punished for any of the evil he had previously done." Hasan Ashyab said instead, "for any of the evil he had previously done.""He will appear, or he will come to appear, over the entire earth, except for the Haram and Bayt al-Maqdis. He will besiege the believers in Bayt al-Maqdis, and they will be shaken with a violent shaking. Then Allah will destroy him and his forces, until even the stump of a wall," or he said, "the base of a wall," and Hasan Ashyab said, "and the root of a tree," will call out, or will say, "O believer," or he said, "O Muslim, here is a Jew," or he said, "here is a disbeliever, come and kill him."He said, "None of that will happen exactly as described until you see matters whose gravity grows in your minds, and you ask one another whether your Prophet had mentioned anything of it to you, and until mountains move from their places, and following that, the seizing of souls will take place."He said, "Then I later attended another sermon of Samura's in which he related this same hadith, and he did not put forward or hold back a single word from its place."Ahmad (20178), whose wording is used here, and Abu Dawud (1184) narrated it, and it was also narrated by Abu Dawud (1184), Tirmidhi (562), Nasai (1484), and Ibn Majah (1264), both at length and in abridged form, and Ibn Khuzayma (1397), Ibn Hibban (2852), and Hakim (1/329–331) all graded it sahih, all of them narrating from the hadith of Aswad bin Qays, who said, "Thalaba bin Abbad Abdi told me," and he related it.Tirmidhi said, "Hasan sahih." Hakim said, "Sahih according to the criterion of the two sheikhs (Bukhari and Muslim)." I say, this is a mistake on his part, for it does not meet the criterion of either of them, since Thalaba bin Abbad is one of the men found only in the Sunan collections. Moreover, no one has confirmed him as reliable. Ibn Hibban merely mentioned him among the reliable narrators in his Thiqat (4/98), and he mentioned no one who narrated from him except Aswad bin Qays, so he is "unknown." As for Hafiz, he said "acceptable," on the basis of Ibn Hibban's mention of him among the reliable narrators, meaning that his hadith is acceptable if corroborated, otherwise it is of weak standing.On this subject there is also a report from Abu Wadak, who said, "Abu Saeed said to me, 'Do the Khawarij acknowledge the Dajjal?' I said, 'No.' He said, 'The Messenger of Allah said, "I am the seal of a thousand prophets, and hardly a prophet was ever sent but he warned his nation about the Dajjal. I have been shown clearly about his matter what was not shown clearly to anyone else. He is one-eyed, while your Lord is not one-eyed. His right eye is blind and bulging, and it is not hidden, looking like phlegm stuck on a plastered wall. His left eye is like a brilliant star. With him will be someone from every tongue. With him will be an image of Paradise, green, with water flowing in it, and an image of the Fire, black, giving off smoke."'"Abdullah bin Ahmad narrated it in his father's Musnad (11752), saying, "I found this hadith in my father's book in his own handwriting, Abdul-Mutaal bin Abdul-Wahhab told us, Yahya bin Saeed Umawi told us, Mujalid told us, from Abu Wadak," and he related it. Hakim also extracted it (2/597) through the route of Mujalid and passed over it in silence, but Dhahabi said, "Mujalid is daif." Haythami mentioned it in al-Majmu (7/347) and said, "Ahmad narrated it, and among its narrators is Mujalid bin Saeed. Nasai judged him reliable in one report, and in another said he is not strong, and a group of scholars judged him daif."I say, Mujalid is Ibn Saeed bin Umayr Hamdani. Most scholars of knowledge judged him daif. Bukhari said of him, "Truthful." In al-Taqrib it says, "Not strong, and he changed in his later years."As for what is reported from Abu Ubayda bin Jarra, who said, "I heard the Prophet say, 'There has been no prophet after Nuh who did not warn his people about the Dajjal, and I warn you about him.'" The Messenger of Allah then described him to us and said, "Perhaps he will be encountered by someone who has seen me and heard my speech." They said, "O Messenger of Allah, how will our hearts be on that day? Like they are today?" He said, "Or even better."Its isnad is daif. Abu Dawud (4756), Tirmidhi (2234), Ahmad (1692–1693), Ibn Hibban (6778), and Hakim (4/542–543) all narrated it, all of them through the route of Khalid Haddan, from Abdullah bin Shaqiq, from Abdullah bin Suraqa, from Abu Ubayda bin Jarra, and he related it. Tirmidhi said, "This is a hasan gharib hadith from the hadith of Abu Ubayda bin Jarra. We do not know it except from the hadith of Khalid Haddan." Hakim said, "This is a hadith sahih in its isnad."I say, in its isnad is Abdullah bin Suraqa, who is Azdi, a follower of the companions, judged reliable by Ajli, and mentioned by Ibn Hibban among the reliable narrators. He is not the same as Adawi, the companion. Bukhari said, "It is not known that he heard from Abu Ubayda." Ibn Kathir said in al-Bidaya wan-Nihaya (1/130), "...there is strangeness in its isnad, and perhaps this occurred before he was shown clearly regarding the matter of the Dajjal what was later shown clearly to him."And Allah, the Exalted, knows best.
