The only sword for which there is proof in the saheeh Sunnah is Dhu’l-Fiqaar. It was narrated from Ibn ‘Abbaas that the Prophet (peace and blessings of Allaah be upon him) acquired his sword Dhu’l-Fiqaar on the day of Badr and this is the one that he saw in a dream on the day of Uhud. It was narrated by al-Tirmidhi (1561) and Ibn Maajah (2808) and classed as hasan by al-Albaani in Saheeh Ibn Maajah. The phrase translated here as “acquired” means he took it in addition to his share of the booty.
