Silsilat al-Ahadith al-Sahihah

Sayyiduna Safinah (may Allah be pleased with him) says that we were on a journey in the company of the Messenger of Allah (peace and blessings be upon him). Whenever a man would get tired, he would place his clothes, shield, sword, etc., on me, until many things gathered upon me to carry. The Prophet (peace and blessings be upon him) said: "You are «سفينه» (i.e., a ship)."
