صحيح البخاري#81Sahihحَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ لأُحَدِّثَنَّكُمْ حَدِيثًا لاَ يُحَدِّثُكُمْ أَحَدٌ بَعْدِي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يَقِلَّ الْعِلْمُ، وَيَظْهَرَ الْجَهْلُ، وَيَظْهَرَ الزِّنَا، وَتَكْثُرَ النِّسَاءُ وَيَقِلَّ الرِّجَالُ، حَتَّى يَكُونَ لِخَمْسِينَ امْرَأَةً الْقَيِّمُ الْوَاحِدُ ".
Narrated Anas:I will narrate to you a Hadith and none other than I will tell you about after it. I heard Allah's Messenger (ﷺ) saying: From among the portents of the Hour are (the following): -1. Religious knowledge will decrease (by the death of religious learned men). -2. Religious ignorance will prevail. -3. There will be prevalence of open illegal sexual intercourse. -4. Women will increase in number and men will decrease in number so much so that fifty women will be looked after by one man
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
