Sahih al-Bukhari, Hadith 6808 ⓘ

Narrated Anas: I will narrate to you a narration which nobody will narrate to you after me. I heard that from the Prophet. I heard the Prophet saying, "The Hour will not be established" or said: "From among the portents of the Hour is that the religious knowledge will betaken away (by the death of religious Scholars) and general ignorance (of religion) will appear; and the drinking of alcoholic drinks will be very common, and (open) illegal sexual intercourse will prevail, and men will decrease in number while women will increase so much so that, for fifty women there will only be one man to look after them."

أَخْبَرَنَا دَاوُدُ بْنُ شَبِيبٍ، حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، أَخْبَرَنَا أَنَسٌ، قَالَ لأُحَدِّثَنَّكُمْ حَدِيثًا لاَ يُحَدِّثُكُمُوهُ أَحَدٌ بَعْدِي، سَمِعْتُهُ مِنَ النَّبِيِّ صلى الله عليه وسلم سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏ "‏ لاَ تَقُومُ السَّاعَةُ ـ وَإِمَّا قَالَ مِنْ أَشْرَاطِ السَّاعَةِ ـ أَنْ يُرْفَعَ الْعِلْمُ وَيَظْهَرَ الْجَهْلُ، وَيُشْرَبَ الْخَمْرُ، وَيَظْهَرَ الزِّنَا، وَيَقِلَّ الرِّجَالُ، وَيَكْثُرَ النِّسَاءُ، حَتَّى يَكُونَ لِلْخَمْسِينَ امْرَأَةً الْقَيِّمُ الْوَاحِدُ ‏" ‏‏.‏
