حدثنا محمد بن محمد بن عصام الكليني - رحمه الله - قال: حدثنا محمد بن يعقوب، عن علان الكليني رفعه إلى أبي عبد الله عليه السلام أنه قال: إنما سمي سيف أمير المؤمنين عليه السلام ذا الفقار لأنه كان في وسطه خطة في طوله تشبه   بفقار الظهر فسمي ذا الفقار لذلك، وكان سيفا نزل به جبرئيل عليه السلام من السماء، وكانت حلقته فضة، وهو الذي نادى به مناد من السماء " لا سيف إلا ذو الفقار، ولا فتى إلا علي ".
12.	We were told by Muhammed bin Muhammed bin ‘Isam al-Kulayni, may Allah grant him mercy, that he said: We were told by Muhammed bin Yaq’ub, from ‘Allan al-Kulayni, that he ascribed to Abu Abdillah, peace be upon him, that he said: The sword of the Commander of the Believers, peace be upon him, was only named Dhu’l-Faqqar because at its center there was a line going along its length similar to the dorsal vertebrae , so it was named Dhu’l-Faqqar for that. It was a sword with which Jibra’eel, peace be upon him, descended from Heaven, and its ring was of silver, and it was he who cried about it from Heaven: There is no sword but Dhu’l-Faqqar, and there is no hero but Ali.
