Narrated Anas:I heard from Allah's Messenger (ﷺ) a narration which none other than I will narrate to you. The Prophet, said, "From among the portents of the our are the following: General ignorance (in religious affairs) will prevail, (religious) knowledge will decrease, illegal sexual intercourse will prevail, alcoholic drinks will be drunk (in abundance), men will decrease and women will increase so much so that for every fifty women there will be one man to look after them."
حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هِشَامٌ، حَدَّثَنَا قَتَادَةُ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ سَمِعْتُ مِنْ، رَسُولِ اللَّهِ صلى الله عليه وسلم حَدِيثًا لاَ يُحَدِّثُكُمْ بِهِ غَيْرِي قَالَ " مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يَظْهَرَ الْجَهْلُ، وَيَقِلَّ الْعِلْمُ، وَيَظْهَرَ الزِّنَا، وَتُشْرَبَ الْخَمْرُ، وَيَقِلَّ الرِّجَالُ، وَيَكْثُرَ النِّسَاءُ، حَتَّى يَكُونَ لِخَمْسِينَ امْرَأَةً قَيِّمُهُنَّ رَجُلٌ وَاحِدٌ ".
