It is narrated from Hazrat Safina (may Allah be pleased with him) that once we were on a journey with the Noble Prophet (peace and blessings be upon him). Whenever someone would get tired, he would hand me his sword, shield, and spear. In this way, I carried many things. The Noble Prophet (peace and blessings be upon him) said, "Today you are performing the task of Safina (a boat)."
