Musnad Abu Ya'la al-Mawsili 117:253

Zuhayr narrated to us, Affan narrated to us, Hammad narrated to us, from Thabit, from Anas, who said: We used to speak that the Hour will not be established until the sky does not rain and the earth does not grow vegetation, and until there is one guardian for fifty women. And until a woman passes by a man, and he takes her and looks at her, and says: "This woman once had a man." Hammad mentioned it in this way. Hammad also mentioned from Thabit, from Anas, from the Prophet (peace be upon him) without doubt. And he also said from Thabit, from Anas, from the Prophet (peace be upon him), as I reckon.
