Does the killer deserve the spoils of the slain (salb)?

Primary text

The killer deserves the spoils of the slain (salb), regardless of whether the Imam explicitly declares it. This view is held by Al-Awza'i, Al-Layth, Al-Shafi'i, Ishaq, Abu Ubaid, and Abu Thawr. The evidence for this is the Prophet's saying, "Whoever kills an enemy combatant, his is his salb." This established ruling was acted upon by the Caliphs afterward, as evidenced by the dispute between Khalid ibn al-Walid and 'Awf ibn Malik regarding a slain enemy's spoils, where 'Awf cited the Prophet's judgment concerning the salb being allocated to the killer. Furthermore, 'Umar's practice of taking the Khums (one-fifth) from the salb of al-Bara' implies that the remainder was the killer's right, as otherwise, 'Umar could not have taken anything if it were entirely the killer's inherent right.
