Anas b. Malik reported Messenger of Allah 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 rainpant.

حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ، حَدَّثَنَا عَبْدُ الْوَارِثِ، حَدَّثَنَا أَبُو التَّيَّاحِ، حَدَّثَنِي أَنَسُ بْنُ،
مَالِكٍ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ
" مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يُرْفَعَ الْعِلْمُ وَيَثْبُتَ
الْجَهْلُ وَيُشْرَبَ الْخَمْرُ وَيَظْهَرَ الزِّنَا " .
