(Religious) ignorance will prevail. -3. Drinking of Alcoholic drinks (will be very common). -4. There will be prevalence of open illegal sexual intercourse.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يُرْفَعَ الْعِلْمُ وَيَثْبُتَ الْجَهْلُ وَيُشْرَبَ الْخَمْرُ وَيَظْهَرَ الزِّنَا  

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.
