"The Messengers of Allah(s.a.w)stood among the people,he praised Allah as is due to Him, then he mentioned the Dajjal and he said: 'Indeed I warn you of him. There has not been a Prophet except that he warned his people, and Nuh indeed warned his people – but I am to say something about him that no Prophet has said to his people: You should know that he is one-eyed, and Allah is certainly not one-eyed.'” Az-Zuhri said: “ `Umar bin Thabit Al-Ansari informed me that some of the Companions of the Prophet(s.a.w) informed him, that one day, the Prophet(s.a.w) was cautioning them against Fitnah and he said: 'You must know that not one of you will ever see his Lord until he dies. And indeed, he(the Dajjal) has “Kafir” written between his eyes; everyone who is averse to his behavior shall read it.'” (Sahih)

Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Seek refuge with Allah from Hellfire. Seek refuge with Allah from the punishment of the grave. Seek refuge with Allah from the sedition of the Dajjal. Seek refuge with Allah from the trials of life and death."

'Amr ibn Shu'ayb reported that his grandfather said, "I heard the Prophet, may Allah bless him and grant him peace, say, 'O Allah, I seek refuge with You from laziness and debt. I seek refuge with You from the trial of the Dajjal. I seek refuge with You from the punishment of the Fire.'"

Allah's Messenger (SAW) said, "When one of you finishes the (last) Tashahhud, he should seek refuge in Allah from four things by saying: 'O Allah I seek refuge in You against the punishment of Jahannam (Hell-fire), the punishment of the grave, the trial of life and death and the evil of the trial of Masih ad-Dajjal (Antichrist)."' [Agreed upon].

"The Messenger of Allah (saw) looked out from a room, when we were talking about the Hour. He said: 'The Hour will not begin until ten signs appear: The rising of the sun from the west (place of its setting); Dajjal; the smoke; the beast; Gog and Magog people; the appearance of 'Eisa bin Maryam(as), the earth collapsing three times - once in the east, one in the west and one in the Arabian Peninsula; and fire that will emerge from the plain of Aden Abyan and will drive the people to the place of Gathering, stopping with them when they stop at night and when they stop to rest at midday."

"I used to wish that I could meet a man among the Companions of the Prophet [SAW] and ask him about the Khawarij. Then I met Abu Barzah on the day of 'Id, with a number of his companions. I said to him: 'Did you hear the Messenger of Allah [SAW] mention the Khawarij?' He said: 'Yes. I heard the Messenger of Allah [SAW] with my own ears, and saw him with my own eyes. Some wealth was brought to the Messenger of Allah [SAW] and he distributed it to those on his right and on his left, but he did not give anything to those who were behind him. Then a man stood behind him and said: "O Muhammad! You have not been just in your division!" He was a man with black patchy (shaved) hair, wearing two white garments. So Allah's Messenger [SAW] became very angry and said: "By Allah! You will not find a man after me who is more just than me." Then he said: "A people will come at the end of time; as if he is one of them, reciting the Qur'an without it passing beyond their throats. They will go through Islam just as the arrow goes through the target. Their distinction will be shaving. They will not cease to appear until the last of them comes with Al-Masih Ad-Dajjal. So when you meet them, then kill them, they are the worst of created beings."

We were talking about the Farewell Pilgrimage without knowing what was it when Messenger of Allah (PBUH) was also present. He (PBUH) stood up and recited the Praise and Glorification of Allah. He then gave a detailed account of Ad-Dajjal and said, 'Every Prophet sent by Allah had warned his people against his mischief. Nuh (PBUH) )warned his nation and so did all the Prophets after him. If he (i.e., Ad-Dajjal) appears among you, his condition will not remain hidden from you. Your Rubb is not one-eyed, but Ad-Dajjal is. His right eye is protruding like a swollen grape. Listen, Allah has made your blood, and your properties as inviolable as of this day of yours (i.e., the Day of Sacrifice), in this city of yours (i.e., Makkah), in this month of yours (i.e., Dhul -Hijjah). Listen, have I conveyed Allah's Message to you?'' The people replied in affirmative. There upon he said, "O Allah, bear witness.'' And he repeated it thrice. He (PBUH) concluded: "Do not revert after me as infidels killing one another".

[Al-Bukhari].

Prophet (saas) would supplicate with these words: "Allahumma inni a'udhu bika min fitnatin-nari wa 'adhabin-nar, wa min fitnatil-qabri wa 'adhabil-qabr, wa min sharri fitnatil-ghina wa min sharri fitnatil-faqr, wa min sharri fitnatil-masihid-dajjal. Allahumma aghsil khatayaya bima'ith-thalfi wal-barad, wa naqqi qalbi minal-khataya kama naqqaytath-thawbal-abyad minad-danas. Wa ba'id bayni wa bayna khatayaya kama ba'adta baynal-mashriqi wal-maghrib. Allahumma inni a'udhu bika minal-kasali wal-harami wal-ma'thami wal-maghrami (O Allah, I seek refuge with You from the tribulation of the Fire and the torment of the Fire, and from the tribulation of the grave, and from the evil of the tribulation of richness and the evil of the tribulation of poverty, and from the evil of the trial of the False Christ. O Allah! Wash away my sins with the water of snow and hail, and cleanse my heart from sin as a white garment is cleansed from filth, and put a great distance between me and my sins, as great as the distance You have made between the east and the west. O Allah! I seek refuge with You from laziness and old age, and from sins and debt)."

Dawud ibn Abi Dawud said, "'Abdullah ibn Salam said to me, 'If you hear that the Dajjal has come out while you are planting young palm trees, it is not too late to plant it, for people will still have livelihood after that."
