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 (a.s.) that he said
"The sword of the Commander of the Believers (a.s.) was only named Dhu’l-Faqar because at its center there was a line going along its length similar to the dorsal vertebrae , so it was named Dhu’l-Faqar for that. It was a sword with which Jibra’il, (a.s.) 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-Faqar, and there is no hero but Ali.'"
