It is narrated about Sayyiduna Anas bin Malik, may Allah be pleased with him, that one day he said: "Shall I not narrate to you a hadith such that after me no one will narrate it to you? I heard it from the tongue of the Prophet Muhammad, peace and blessings be upon him. I heard the Prophet Muhammad, peace and blessings be upon him, say: 'The Hour will not be established (the narrator is in doubt, perhaps these are the words) and among the signs of the Hour is that knowledge will be taken away, ignorance will become widespread, wine will be drunk, adultery will become common, and men will decrease while women will increase, to the extent that one man will be the guardian of fifty women.'"
