Introduction

Among the signs of the Last Hour is the appearance of approximately 30 false claimants of Prophethood known as Dajjals.
Narrated Abu Hurayrah: Allah's Apostle said:

"The Hour will not be established until two big groups fight each other whereupon there will be a great number of casualties on both sides and they will be following one and the same religious doctrine, until about 30 dajjals appear, and each of them will claim that he is Allah's Apostle..."

(Related by Bukhari and Muslim)

The last of these Dajjals would be the False Messiah:

Once the Prophet of Allah said, while delivering a ceremonial speech at an occasion of a solar eclipse, as Samura son of Jundub reported:

"...Verily by God, the Last Hour will not come until 30 liars of prophecy will appear and the final one will be the One-eyed False Messiah."

(Narrated by Imam Ahmad as a sound Hadeeth).

In another authentic hadeeth, the Prophet of Allah informed that of 27 dajjals, 4 of them would be women:

Huthaifa narrated, that the Prophet said:

"In my Ummah (community/nation), there are 27 dajjals of liars, including 4 women (who will proclaim themselves Prophets). I am the last Prophet and none will come after me."

(Related by Imam Ahmad and Al-Tabrani as a sound hadeeth)

Therefore, there would be 27-30 Dajjals who would appear, 4 of which would be women and the last of which would be the False Messiah, who the true Messiah, Prophet 'Eessa ("Jesus") would kill. The Prophet of Allah (Prophet Muhammad) already closed the loophole of building a series of Prophets and confirmed the impossibility of any newcomer as a Prophet after him. The dajjals he mentioned that have already appeared are discussed below. As I find more of them, I shall list them:
