It is narrated from Khalifah bin Khayyat that the kunyah of al-Fadl bin Abbas bin Abd al-Muttalib bin Hashim was Abu Muhammad. He took part with the Messenger of Allah (peace and blessings be upon him) in the campaigns of Makkah and Hunayn, and stood firm when the people turned their backs and fled. He was also present at the Farewell Hajj, and was among those who washed the Messenger of Allah (peace and blessings be upon him) and took charge of his (peace and blessings be upon him) burial. Then he set out for Syria for jihad, and died in the region of Jordan during the plague of Amwas in the year 18 AH, during the caliphate of Sayyiduna Umar bin al-Khattab (may Allah be pleased with him).

Yahya bin Ma'in says that al-Fadl bin Abbas (may Allah be pleased with him) was martyred on the day of the Battle of Yarmuk, during the caliphate of Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him).

Ibn Ishaq states that the kunyah of al-Fadl bin Abbas bin Abd al-Muttalib was Abu Muhammad, and his mother was Umm al-Fadl, whose name was Lubabah bint al-Harith. He was martyred (while fighting in jihad) with the army of Sayyiduna Khalid bin al-Walid (may Allah be pleased with him) during the caliphate of Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him).
