It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that on the day of the Battle of Badr, we were three men riding on one camel each. In this way, Sayyiduna Abu Lubabah (may Allah be pleased with him) and Sayyiduna Ali (may Allah be pleased with him) were companions of the Prophet (peace and blessings be upon him). When it was the Prophet’s (peace and blessings be upon him) turn to walk on foot, both of them said, "We will walk in your place (you remain riding)." The Prophet (peace and blessings be upon him) said: "You two are not stronger than me, nor am I in less need of reward than you."
