باب رَفْعِ الْعِلْمِ وَقَبْضِهِ وَظُهُورِ الْجَهْلِ وَالْفِتَنِ فِي آخِرِ الزَّمَانِ

Abu Huraira reported Allah's Messenger (ﷺ) as saying:

(When) the time would draw close to the Last Hour, knowledge would be snatched away, turmoil would be rampant, miserliness would be put (in the hearts of the people) and therewould be much bloodshed. They said: What is al-harj? Thereupon he said: It is bloodshed.
حَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، حَدَّثَنِي حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ، أَنَّ أَبَا هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ يَتَقَارَبُ الزَّمَانُ وَيُقْبَضُ الْعِلْمُ وَتَظْهَرُ الْفِتَنُ وَيُلْقَى الشُّحُّ وَيَكْثُرُ الْهَرْجُ ‏"‏ ‏.‏ قَالُوا وَمَا الْهَرْجُ قَالَ ‏"‏ الْقَتْلُ ‏"‏ ‏.‏
