Hadith 5364
وَعَنْ حُذَيْفَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «لَا تَقُومُ السَّاعَةُ حَتَّى تَقْتُلُوا إِمَامَكُمْ وَتَجْتَلِدُوا بأسيافكم ويرَث دنياكم شرارُكم» . رَوَاهُ التِّرْمِذِيّ
It is narrated from Hudhayfah (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "The Hour will not be established until you kill your caliph, fight and kill one another, and your evil ones become the inheritors of your world." Its chain is Hasan. Narrated by al-Tirmidhi.
