Sayyiduna Buraydah (may Allah be pleased with him) narrates: On a journey I was with the Prophet (peace and blessings be upon him). Whenever anything was left over, the Prophet (peace and blessings be upon him) would have me carry it, and he named me "al-Zamilah" (the pack-camel).
Al-Bazzar recorded it, and its chain is hasan (good).
