Sunan Ibn Majah, Book 36, Hadith 125 (In-Book) ⓘ
It was narrated from ‘Abdullah that the Messenger of Allah said: “Just before the Hour, there will be days when knowledge will disappear, ignorance will become widespread and there will be much Harj. And Harj means killing.”
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبِي وَوَكِيعٌ، عَنِ الأَعْمَشِ، عَنْ شَقِيقٍ، عَنْ عَبْدِ اللَّهِ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " يَكُونُ بَيْنَ يَدَىِ السَّاعَةِ أَيَّامٌ يُرْفَعُ فِيهَا الْعِلْمُ وَيَنْزِلُ فِيهَا الْجَهْلُ وَيَكْثُرُ فِيهَا الْهَرْجُ " . وَالْهَرْجُ الْقَتْلُ .
