٢ - حَدَّثَنا أَبي رَضِىَ اللهُ عَنْهُ قالَ: حَدَّثَنا سَعْدِ بْنِعَبْدِ اللَّه عَنْ مُحَمَّدِ بْنِ عِيسَى بْنِ عُبِيْد قالَ إِنَّ مُحَمَّدَ بْنَ عَبْدِ اللَّهِ الطَّاهِرِيَّ كَتَبَ إِلَى الرِّضَايَشْكُو عَمَّهُ بِعَمَلِ السُّلْطَانِ وَالتَّلَبُّسِ بِهِ وَأَمْرَ وَصِيَّتِهِ فِي يَدَيْهِ فَكَتَبَ‏ عَلَيْهِ السَّلامُ أَمَّا الْوَصِيَّةُ فَقَدْ كُفِيتَ أَمْرَهَا فَاغْتَمَّ الرَّجُلُ فَظَنَّ أَنَّهَا تُؤْخَذُ مِنْهُ فَمَاتَ بَعدَ ذَلِكَ بِعِشْرِينَ يَوْماً
47-2 (The author of the book narrated) my father - may God be pleased with him - narrated that Sa’d ibn Abdullah quoted on the authority of Muhammad ibn Isa ibn Obayd, “Muhammad ibn Abdullah al-Taheri wrote to Ar-Ridha’  and complained about his uncle who worked for the King; wears their official clothes; and that the affairs of the (King’s) Trusteeship are in the hands of his uncle. The Imam  wrote him back and said, ‘Regarding the issue of the (King’s) Trusteeship you have become self-sufficient and this problem will soon be solved.’ Muhammad became extremely worried and thought that he would be dismissed from being in charge of this affair, but he died twenty days later.”
