Origin
Two swords were captured from the temple of Manat in the Raid of Sa'd ibn Zaid al-Ashhali. Muhammad gave them to Ali, saying that one of them was Dhulfiqar, which became the famous sword of Ali and a symbol of Shia Islam
"Zulfiqar" and phonetic variations have been popular given names, as with former Pakistani Prime Minister Zulfikar Ali Bhutto. Variously spelled variations exist in modern language scripts.
