Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates: On the occasion of the Battle of Badr, three men rode one camel. Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) and Sayyiduna Abu Lubabah (may Allah be pleased with him) were with the Prophet (peace and blessings be upon him). When it was the Prophet's (peace and blessings be upon him) turn (to walk), the two of them submitted: "We will walk in your place." The Prophet (peace and blessings be upon him) said: "You two are not stronger than I am, and I am not less in need of the reward than you two."
Ahmad and al-Bazzar recorded it. He (al-Bazzar) recorded these words: When it was the Prophet's (peace and blessings be upon him) turn, the two of them submitted: "Stay mounted; we will walk in your place." The rest of the narration is as before. Its chain contains a narrator, Asim bin Bahdalah, whose hadith is hasan (good). The remaining narrators of Ahmad are the narrators of the Sahih.
