Al-Zuhri (may Allah have mercy on him) said: "The Messenger of Allah (peace and blessings be upon him) assigned full shares on the day of Badr to a number of the Muhajirun and the Ansar, even though they were not present at it because of an excuse they had. Among them, from the Ansar, were Abu Lubabah bin Abd al-Mundhir and al-Harith bin Hatib (may Allah be pleased with them both)."
