Chapter 8 | The obligation to obey the Imams
10ـ وَبِهَذَا الاسْنَادِ عَنْ مَرْوَكِ بْنِ عُبَيْدٍ عَنْ مُحَمَّدِ بْنِ زَيْدٍ الطَّبَرِيِّ قَالَ كُنْتُ قَائِماً عَلَى رَأْسِ الرِّضَا بِخُرَاسَانَ وَعِنْدَهُ عِدَّةٌ مِنْ بَنِي هَاشِمٍ وَفِيهِمْ إِسْحَاقُ بْنُ مُوسَى بْنِ عِيسَى الْعَبَّاسِيُّ فَقَالَ يَا إِسْحَاقُ بَلَغَنِي أَنَّ النَّاسَ يَقُولُونَ إِنَّا نَزْعُمُ أَنَّ النَّاسَ عَبِيدٌ لَنَا لا وَقَرَابَتِي مِنْ رَسُولِ الله ﷺ مَا قُلْتُهُ قَطُّ وَلا سَمِعْتُهُ مِنْ آبَائِي قَالَهُ وَلا بَلَغَنِي عَنْ أَحَدٍ مِنْ آبَائِي قَالَهُ وَلَكِنِّي أَقُولُ النَّاسُ عَبِيدٌ لَنَا فِي الطَّاعَةِ مَوَالٍ لَنَا فِي الدِّينِ فَلْيُبَلِّغِ الشَّاهِدُ الْغَائِبَ.
10. Through the same chain of narrators it is narrated from Marwak ibn ‘Ubayd from Muhammad ibn Zayd al-Tabari who has said the following. “I was in the presence of Imam al-Rida in Khurasan with a group of Hashimite people among them was Issshaq ibn Musa ibn ‘Isa from Abbasides and the Imam said to Ishaq, “I hear that people say we think they are our slaves. I swear upon my close relation with the holy Prophet (s.a.) that I have never said such a thing nor Have I ever heard any such thing from my father and grandfather nor I have received any such report from my (holy and noble) ancestors who may have said any such thing. But I must say that people are our slaves in the matters of obedience to us. They are our friends in religion. Those present here must tell this to those who are not present here.”
