Musnad Abu Ya'la al-Mawsili 115:244

Zuhayr narrated to us, Yazid ibn Harun narrated to us, Sa'id ibn Abi 'Arubah narrated to us, from Qatadah, from Anas, who said: "Shall I not narrate to you a hadith that no one will narrate to you after me, which I heard from the Messenger of Allah (may Allah bless him and grant him peace)? He said: 'Among the signs of the Hour are that knowledge will be lifted, ignorance will descend, wine will be drunk, women will increase, and men will decrease, until one man will be the guardian of fifty women.'"
