The Taking Away Of Knowledge And The Spread Of Ignorance At The End Of Time
Sahih Muslim
حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا عَبْدُ الْوَارِثِ، حَدَّثَنَا أَبُو التَّيَّاحِ، حَدَّثَنِي أَنَسُ بْنُ، مَالِكٍ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يُرْفَعَ الْعِلْمُ وَيَثْبُتَ الْجَهْلُ وَيُشْرَبَ الْخَمْرُ وَيَظْهَرَ الزِّنَا " .
Anas b. Malik reported Allah's Messenger (ﷺ) as saying: It is from the conditions of the Last Hour that knowledge would be taken away and ignorance would prevail (upon the world), the liquor would be drunk, and adultery would become rampant.
