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 ـ صلى الله عليه وسلم ـ 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 ‏"‏ ‏.‏

It was narrated that Anas bin Malik said: “Shall I not tell you aHadith that I heard from the Messenger of Allah (PBUH), which no onewill tell you after me? I heard it from him (saying): ‘Among theportents of the Hour are that knowledge will be taken away andignorance will prevail, illegal sex will become widespread and winewill be drunk, and men will disappear and women will be left, untilthere is one man in charge of fifty women.” Translation Not Available
