Sunan al-Shafi'i

Aswad bin Qais (may Allah have mercy on him) narrates from a man of his tribe whose name is Seer bin Alqamah (may Allah be pleased with him). He said: I fought in single combat with a man in the Battle of Qadisiyyah whose equipment reached up to (12) thousand. Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) gave all of it to me as a reward.
