Qiyamah will not be established until about 30 Dajjal appear.
Prophet Muhammad (صلی اللہ علیہ وآلہ وسلم ) informed the Ummah about the troubles, unrests and about the liars, dajjals who will claim Prophethood. Accordingly in The Collection of Tirmidhi, a tradition runs as” In my Ummah 30 liars will be there. Each one of them will lay claim to Prophethood, even though there is no Prophet after Me." Jame' Tirmidhi Chapters of Trials. Also Sahih Bukhari, Kitaab ul Manaqib, baab alamaat e Nubuwwa fil Islam has a Tradition, " Qiyamah will not be established until about 30 Dajjals, liars appear and each one will claim that he is the prophet of Allah."
