Anas bin 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), khamr would be drunk, and zina would become rampant.
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 ” .
