It was narrated that Anas bin Malik said:
“Shall I not tell you a Hadith that I heard from the Messenger of Allah ﷺ, which no one will tell you after me? I heard it from him (saying): ‘Among the portents of the Hour are that knowledge will be taken away and ignorance will prevail, illegal sex will become widespread and wine will be drunk, and men will disappear and women will be left, until there is one man in charge of fifty women.”

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، سَمِعْتُ قَتَادَةَ، يُحَدِّثُ عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ أَلاَ أُحَدِّثُكُمْ حَدِيثًا سَمِعْتُهُ مِنْ، رَسُولِ اللَّهِ ﷺ لاَ يُحَدِّثُكُمْ بِهِ أَحَدٌ بَعْدِي سَمِعْتُهُ مِنْهُ " إِنَّ مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يُرْفَعَ الْعِلْمُ وَيَظْهَرَ الْجَهْلُ وَيَفْشُوَ الزِّنَا وَيُشْرَبَ الْخَمْرُ وَيَذْهَبَ الرِّجَالُ وَيَبْقَى النِّسَاءُ حَتَّى يَكُونَ لِخَمْسِينَ امْرَأَةً قَيِّمٌ وَاحِدٌ " .
