Musnad Abu Ya'la al-Mawsili 115:338

Abu Musa narrated to us, Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, he said: I heard Qatadah narrating from Anas ibn Malik, who said: Shall I not narrate to you a hadith I heard from the Messenger of Allah (may Allah bless him and grant him peace)—no one will narrate it to you after me, having heard it from him? Indeed, among the signs of the Hour are that knowledge will be lifted, ignorance will appear, adultery will become widespread, wine will be drunk, men will depart, and women will remain, until for fifty women there is one guardian.
