 ٣ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ صَفْوَانَ عَنْ أَبِي الْحَسَنِ الرِّضَا (عَلَيْهِ السَّلام) قَالَ كَانَ أَبُو جَعْفَرٍ (عَلَيْهِ السَّلام) يَقُولُ إِنَّمَا مَثَلُ السِّلاحِ فِينَا مَثَلُ التَّابُوتِ فِي بَنِي إِسْرَائِيلَ حَيْثُمَا دَارَ التَّابُوتُ أُوتُوا النُّبُوَّةَ وَحَيْثُمَا دَارَ السِّلاحُ فِينَا فَثَمَّ الامْرُ قُلْتُ فَيَكُونُ السِّلاحُ مُزَائِلاً لِلْعِلْمِ قَالَ لا.
 3. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan from abu a1-Hassan al-Rida  who has said the following. “Abu Ja‘far  would say, ‘The case of the Armaments with us is as the Ark with the Israelites. Wherever the Ark would go prophet-hood would also follow. Wherever the Armaments among us would go the matter (leadership with Divine authority) would also settle there.” I then asked, “Would the Armaments ever depart knowledge?” The Imam  said, “No, it would not do so.”
