Appearance of Dajjal
First of all, we will quote the reports which mention the liars and "dajjals" who will precede the coming off the Dajjal, (or Antichrist), who will be the last of them; may Allah curse them and punish them with Hell-fire.
Jabir Ibn Samurah said, "I heard the Prophet say, 'Just before the Hour there will be many liars.'" Jabir said, "Be on your guard against them." (Muslim).
Jabir said, "I heard the Prophet say, 'Just before the Hour there will be many liars; among them is the one in al-Yamamah, the 'Ansi in San'a', the one in Himyar, and the Dajjal. This will be the greatest fitnah.''' (Ahmad)
Abu Hurayrah said, "The Prophet said, "The Hour will not come ... until nearly 30 "dajjals" (liars) appear, each one claiming to be a messenger from Allah.'" (al-Bukhari Muslim.)
Abu Hurayrah said, "The Prophet said, 'The Hour will not come until 30 "dajjals" appear, each of them claiming to be a messenger from Allah, wealth increases, tribulations appear and al-Harj increases.'" Someone asked, 'What is al-Harj?' He said, 'Killing, killing.' (Ahmad)
Abu Hurayrah said, "The Prophet said, 'The Hour will not come until 30 "dajjals" appear, all of them lying about Allah and His Messenger." (Abu Dawud)
Abu Hurayrah said, "The Prophet said, 'Just before the Hour, there will be 30 "dajjals", each of whom will say, I am a Prophet.'" (Ahmad)
Abu Hurayrah said, "The Prophet said, 'There will be "dajjals" and liars among my Ummah. They will tell you something new, which neither you nor your forefathers have heard. Be on your guard against them, and do not let them lead you astray.'" (Ahmad)
Thawban said, "The Prophet said, 'There will be 30 liars among my Ummah. Each one will claim that he is a prophet; but I am the last of the Prophets (Seal of the Prophets), and there will be no Prophet after me.'" (Ahmad)
The Prophet said, "Verily before the Day of Resurrection there will appear the Dajjal, and 30 or more liars." (Ahmad)
Ibn 'Omar said, "I heard the Prophet say, 'Among my Ummah there will be more than 70 callers, each of whom will be calling people to Hell-fire. If I wished, I could tell you their names and tribes.'"
Abu Bakrah said, "The people spoke a great deal against Musaylimah before the Prophet said anything about him. Then the Prophet got up to give a speech and said: '...as for this man about whom you have spoken so much - he is one of the 30 liars who will appear before the Hour, and there is no town which will not feel the fear of the Antichrist.'" (Ahmad)
In another version of this report, the Prophet said, "He is one of the 30 liars who will appear before the Dajjal. There is no town which will escape the fear of the Dajjal, apart from Madînah. At that time there will be two angels at every entrance of Madina, warding off the fear of the Antichrist." Anas Ibn Malik said, "The Prophet said, 'The time of the Dajjal will be years of confusion. People will believe a liar, and disbelieve one who tells the truth. People will distrust one who is trustworthy, and trust one who is treacherous; and the Ruwaybidah will have a say.' Someone asked, 'Who are the Ruwaybidah?' He said, 'Those who rebel against Allah and will have a say in general affairs.'" (Ahmad)
