5ـ أَحْمَدُ بْنُ مُحَمَّدٍ وَمُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحَسَنِ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ الله عَنْ أَبِي الْحَسَنِ الرِّضَا (عَلَيْهِ السَّلام) قَالَ سَأَلْتُهُ عَنْ ذِي الْفَقَارِ سَيْفِ رَسُولِ الله (صَلَّى اللهُ عَلَيْهِ وَآلِه) مِنْ أَيْنَ هُوَ قَالَ هَبَطَ بِهِ جَبْرَئِيلُ (عَلَيْهِ السَّلام) مِنَ السَّمَاءِ وَكَانَتْ حِلْيَتُهُ مِنْ فِضَّةٍ وَهُوَ عِنْدِي.
5. Ahmad ibn Muhammad and Muhammad ibn Yahya have narrated from Muhammad ibn al-Hassan from Muhammad ibn ‘Isa from Ahmad ibn Abi ‘Abdillah who has said that he asked Abi al-Hassan al-Redha (a.s.) about Dhulfaqar, the sword of the Messenger of Allah as to where it was from. The Imam (a.s.) said, “Jibril came down with it from the heavens. It was decorated with silver and it is with me (now).”
