[1] Al-Kāfī corroborates that this refers to Dhū’l-Faqār, the sword of the Prophet صلى الله عليه وعلى آله and famous for its ownership and use by ʿAlī صلوات الله عليه after him. See below: أَحْمَدُ بْنُ مُحَمَّدٍ وَمُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحَسَنِ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ الله عَنْ أَبِي الْحَسَنِ الرِّضَا عليه السلام قَالَ: سَأَلْتُهُ عَنْ ذِي الْفَقَارِ سَيْفِ رَسُولِ الله صلى الله عليه وعلى آله: مِنْ أَيْنَ هُوَ قَالَ: هَبَطَ بِهِ جَبْرَئِيلُ عليه السلام مِنَ السَّمَاءِ وَكَانَتْ حِلْيَتُهُ مِنْ فِضَّةٍ وَهُوَ عِنْدِي. Aḥmad b. Muḥammad and Muḥammad b. Yaḥyā, from Muḥammad b. al-Ḥasan, from Muḥammad b. ʿĪsā, from Aḥmad b. Abī ʿAbd Allāh, from Abī’l-Ḥasan al-Riḍā عليه السلام. Aḥmad narrated: “I asked him about Dhī’l-Faqār, the sword of the Apostle of Allāh صلى الله عليه وعلى آله: “From where did it come?” He said: “Jibraʾīl عليه السلام brought it down from heaven. It had a hilt of silver, and I have it (now).” From al-Kāfī—Vol. 1, Book 4—“The Book of Divine Authority”—chapter 38/95, tradition no. 5, p. 138.
