Maulana Ataullah Sajid
Benefits and Issues:
➊ Allah Almighty has designated one-fifth of the spoils of war (ghanimah) for Allah and His Messenger. (Surah Al-Anfal, verse: 41) In an Islamic government, this portion is deposited into the public treasury (Bayt al-Mal) and spent on the collective needs of the Muslims.
➋ The Messenger of Allah (sallallahu alayhi wa sallam) used to fulfill his personal expenses from the one-fifth share of the spoils (khums). Therefore, for the need of jihad, he also took a sword from the khums.
➌ This sword is called Dhu’l-Fiqar because it had some deep marks on it, similar to the vertebrae of the spine. (See: Al-Nihayah by Ibn Athir, under the root "faqar")
