The Prophet ﷺ said, "Near the establishment of the Hour, there will be the days of Al-Harj, and the religious knowledge will be taken away (vanish i.e. by the death of Religious scholars) and general ignorance will spread." Abu Musa said, "Al-Harj, in the Ethiopian language, means killing."
بَيْنَ يَدَىِ السَّاعَةِ أَيَّامُ الْهَرْجِ يَزُولُ الْعِلْمُ وَيَظْهَرُ فِيهَا الْجَهْلُ قَالَ أَبُو مُوسَى وَالْهَرْجُ الْقَتْلُ بِلِسَانِ الْحَبَشَةِ
[Machine] "And I think that he, the Prophet ﷺ, said before the Day of Judgment, there will be days of chaos, days during which knowledge will fade away, and ignorance will prevail. Abu Musa said that 'huruj' (chaos) means killing in the Abyssinian language."
وَأَحْسَبُهُ رَفَعَهُ إِلَى النَّبِيِّ ﷺ أَنَّهُ قَالَ بَيْنَ يَدَيِ السَّاعَةِ أَيَّامُ الْهَرْجِ أَيَّامٌ يَزُولُ فِيهَا الْعِلْمُ وَيَظْهَرُ فِيهَا الْجَهْلُ فَقَالَ أَبُو مُوسَى الْهَرْجُ بِلِسَانِ الْحَبَشِ الْقَتْلُ
