"The Messenger of Allah said: 'One of the portents of the Hour will be that wealth becomes widespread and abundant, and trade will become widespread, but knowledge will disappear. A man will try to sell something and will say: "No, not until I consult the merchant of banu so and so: and People will look throughout a vast area for a scribe and will not find one." (Sahih )
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ قَالَ حَدَّثَنِي ابْنُ جَرِيرٍ قَالَ حَدَّثَنِي أَبِي عَنْ يُونُسَ عَنِ الْحَسَنِ عَنْ عَمْرِو بْنِ تَغْلِبَ قَالَ
قَالَ رَسُولُ اللهِ ﷺ إِنَّ مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يَفْشُوَ الْمَالُ وَيَكْثُرَ وَتَفْشُوَ التِّجَارَةُ وَيَظْهَرَ الْجَهْلُ وَيَبِيعَ الرَّجُلُ الْبَيْعَ فَيَقُولَ حَتَّى أَسْتَأْمِرَ تَاجِرَ بَنِي فُلَانٍ وَيُلْتَمَسَ فِي الْحَيِّ الْعَظِيمِ الْكَاتِبُ فَلَا يُوجَدُ
