محمد بن الحسن الصفار، قال: حدّثنا محمد بن الحسين بن أبي الخطاب، ومحمد بن عيسى بن عبيد اليقطيني، جميعاً، عن عبدالرحمن بن أبي نجران، عن عيسى بن عبداللّه بن محمد بن عمر بن علي بن أبي طالب، عن خاله الصادق جعفر بن محمد عليهما السلام، قال: قلت له: إنْ كان كونٌ—لا أراني الله يومك—فبمن أئتمّ؟ فأومأ الى موسى عليه السلام، فقلت: فان مضى موسى فالى من؟ قال: الى ولده، قلت: فان مضى ولده، وترك أخاً كبيراً وابناً صغيراً، فبمن أئتمّ؟ قال: بولده، ثمّ قال: هكذا أبداً، قلت: فإنّ أنا لم أعرفه ولم أعرف موضعه، فما أصنع؟ قال: تقول: (اللّهمّ إني أتولّى من بقي من حججك من ولد الامام الماضي) فان ذلك يجزيك. ورواه عن سعد والحميري عن ابن أبي الخطاب وابن عبيد.
Muḥammad b. al-Ḥasan al-Ṣaffār said: “Muḥammad b. al-Ḥusayn b. Abī’l-Khaṭṭāb and Muḥammad b. ʿĪsā b. ʿUbayd al-Yaqṭīnī altogether narrated to us, from ʿAbd al-Raḥmān b. Abī Najrān, from ʿĪsā b. ʿAbd Allāh b. Muḥammad b. ʿUmar b. ʿAlī b. Abī Ṭālib, from his maternal uncle al-Ṣādiq, Jaʿfar b. Muḥammad (as-d). ʿĪsā al-ʿAlawī narrated: “I said to him: “If something were to happen—may Allāh not let me see your day—who would I take as my Imam?” He nodded in the direction of Mūsā (as). I continued: “If Mūsā were to die, then to whom?” He said: “To his son.” I said: “If his son were to die, and leave behind a brother who is older and a son who is younger, who do I take as my Imam?” He said: “His son.” Then, he said: “It will always be as such.” I followed up with: “If I am not cognisant of him, nor do I recognise his whereabouts, what am I to do?” He responded: “You say: O’ Allāh, I seek to take as authority over me whoever remains of Your Divine authorities from among the posterity of the late Imam, for that will suffice you.” This has also been transmitted by way of Saʿd and al-Ḥimyarī, from Ibn Abī’l-Khaṭṭāb, from Ibn ʿUbayd.
