Chapter 73 | Tacit and Explicit Testimony as proof of abu Ja‘far al-Thani’s (the second) Divine Authority over the people after abu al-Hassan al-Rida
6ـ أَحْمَدُ بْنُ مِهْرَانَ عَنْ مُحَمَّدِ بْنِ عَلِيٍّ عَنْ مُعَمَّرِ بْنِ خَلادٍ قَالَ ذَكَرْنَا عِنْدَ أَبِي الْحَسَنِ شَيْئاً بَعْدَ مَا وُلِدَ لَهُ أَبُو جَعْفَرٍ فَقَالَ مَا حَاجَتُكُمْ إِلَى ذَلِكَ هَذَا أَبُو جَعْفَرٍ قَدْ أَجْلَسْتُهُ مَجْلِسِي وَصَيَّرْتُهُ فِي مَكَانِي.
6. Ahmad ibn Mihran has narrated from Muhammad ibn Ali from Mu‘ammar ibn Khallad who has said the following. “Once in the presence of abu al-Hassan we spoke about an issue, Imamat, (Leadership with Divine Authority). It was after the birth oof abu Ja‘far . The Imam said, “You do not need any such thing (thinking who the Imam will be). This is abu Ja‘far . I have placed him in my own place and made him to assume my position.”
