Muhammad bin Ishaq (may Allah have mercy on him) said: "Abu Lubabah bin Abd al-Mundhir bin Zanbar bin Umayyah bin Zayd bin Malik bin Awf bin Amr bin Awf bin Malik bin al-Aws set out with the Prophet (peace and blessings be upon him) towards Badr, but he (peace and blessings be upon him) sent him back and appointed him governor of Madinah, and he assigned him his share as well and counted him among the people of Badr."
