Hadith on the Hour: Among signs of the Hour are ignorance, adultery, and an increase of women

Anas ibn Malik reported: I will narrate traditions which no one after me can narrate. I heard the Messenger of Allah, peace be upon him, say, “Among the signs of the Hour are that knowledge will decrease, ignorance will prevail, adultery will become widespread, and women will increase and men will decrease until a single man must care for fifty women.”

[Sahih Bukhari, Book 3, Number 81]

عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ لَأُحَدِّثَنَّكُمْ حَدِيثًا لَا يُحَدِّثُكُمْ أَحَدٌ بَعْدِي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يَقِلَّ الْعِلْمُ وَيَظْهَرَ الْجَهْلُ وَيَظْهَرَ الزِّنَا وَتَكْثُرَ النِّسَاءُ وَيَقِلَّ الرِّجَالُ حَتَّى يَكُونَ لِخَمْسِينَ امْرَأَةً الْقَيِّمُ الْوَاحِدُ
