عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنِ الْمُفَضَّلِ بْنِ مَزْيَدٍ عَنْ أَبِي عَبْدِ اللَّهِ (عليه السلام) قَالَ قُلْتُ لَهُ أَيَّامَ عَبْدِ اللَّهِ بْنِ عَلِيٍّ قَدِ اخْتَلَفَ هَؤُلَاءِ فِيمَا بَيْنَهُمْ فَقَالَ دَعْ ذَا عَنْكَ إِنَّمَا يَجِي‏ءُ فَسَادُ أَمْرِهِمْ مِنْ حَيْثُ بَدَا صَلَاحُهُمْ.
257. Ali Bin Ibrahim, from his father, from Ibn Abi ‘Umayr, from Al-Mufazzal Bin Mazeed, who has narrated the following: I said to Abu Abdullah , ‘The days of Abdullah Bin Ali, they (Abbasid rulers) disputed regarding what was in between them’. So he  said: ‘You leave that. But rather, the spoiling of their command would come from where their success began’.
