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..."
