Battle of Hunayn
Fadl was the eldest son of Al-‘Abbas ibn ‘Abd al-Muttalib, an uncle of Muhammad and a wealthy merchant of Mecca, and of Lubaba bint al-Harith, a sister of Muhammad's wife Maymuna. He was among those who "stood firm" at the Battle of Hunayn in 630, after which his family emigrated to Medina.
