Mishkat al-Masabih, 3710

Abu Dharr reported God's Messenger as saying, “How will you deal with <i>imams</i> after my death who appropriate to themselves this booty?” He replied, “I swear by Him who sent you with the truth that I shall put my sword on my shoulder and smite with it till I meet you.” He said, “Shall I not guide you to something better than that? You must show endurance till you meet me.” Abu Dawud transmitted it.

وَعَنْ أَبِي ذَرٍّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «كَيْفَ أَنْتُمْ وَأَئِمَّةً مِنْ بَعْدِي يَسْتَأْثِرُونَ بِهَذَا الْفَيْءِ؟» . قُلْتُ: أَمَا وَالَّذِي بَعَثَكَ بِالْحَقِّ أَضَعُ سَيْفِي عَلَى عَاتِقِي ثُمَّ أَضْرِبُ بِهِ حَتَّى أَلْقَاكَ قَالَ: «أَوَلَا أَدُلُّكَ عَلَى خَيْرٍ مِنْ ذَلِكَ؟ تَصْبِرُ حَتَّى تَلقانِي» . رَوَاهُ أَبُو دَاوُد
