Sahih al-Bukhari 5577

Muslim ibn Ibrāhīm narrated to us: Hishām narrated to us: Qatādah narrated to us, from Anas (may God be pleased with him), who said: “I heard a report from the Messenger of God ﷺ that no one but me will relate to you. He said: ‘Among the signs of the Hour are that ignorance will become widespread, knowledge will diminish, fornication will become widespread, wine will be drunk, men will grow fewer and women more numerous, until one man will be responsible for fifty women.’”
