Our Prophet (pbuh) informed that the PKK would operate in 3 branches, and embrace materialist ideology and their leader’s name would be Abdullah Öcalan

There will be around the Euphrates, near Ash-Sham or a little after it, a great assembly (of armies). They will fight each other over wealth, and seven out of every nine will be killed. And that will be after the Al-Hadda (powerful, hammering sound) and the Al-Wahiya (catastrophe) in the month of Ramadan, and after the split resulting in THREE BANNERS, each will seek the kingship (reign) for himself, AMONG THEM IS A MAN WHOSE NAME IS ABDULLAH.

(Nuaim ibn Hammad's Kitab Al-Fitan, hadith No: 971)
