Imam Ahmad : 22213

حَدَّثَنَا سُلَيْمَانُ أَخْبَرَنَا إِسْمَاعِيلُ حَدَّثَنِي عَمْرٌو عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ الْأَشْهَلِ عَنْ حُذَيْفَةَ بْنِ الْيَمَانِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا تَقُومُ السَّاعَةُ حَتَّى تَقْتُلُوا إِمَامَكُمْ وَتَجْتَلِدُوا بِأَسْيَافِكُمْ وَيَرِثُ دِيَارَكُمْ شِرَارُكُمْ

Narrated to us [Sulaiman] Narrated to us [Isma'il] has told me ['Amru] and ['Abdullah bin 'Abdur Rahman Al Asyhal] from [Hudzaifah bin Al Yaman] that the Prophet Peace be upon him wa salam said: "The Hour will not come until you kill your leader, you slash him with your swords while he inherits your houses and your vices.
