Acceptance of Islam Sa'd was among the leading figures among the
Ansar, as Muhammad had called the people of
Aws and
Khazraj from Medina who converted to Islam. He converted at the hands of
Mus'ab ibn Umair. His conversion led to the immediate conversion of his entire subtribe of the Aus, the Banu Abdul-Ashhal:
Confrontation with Abu Jahl and the start of Badr hostilities Before the
Battle of Badr, Sa'd had visited Mecca once to perform his Umrah with his non-Muslim friend
Umayyah ibn Khalaf, when they came across
Abu Jahl. They argued, and as it became heated, Sa'd threatened Abu Jahl with preventing his safe passage through Medina if he stopped the Muslims from performing the pilgrimage in Mecca. Narrated 'Abdullah bin Mas'ud:
Battle of Badr The Muslims originally expected a much smaller Meccan force and were surprised by the large Meccan Army so
Muhammad called Shura:
Battle of Uhud Sa'd was one of the few companions who remained on the battlefield, when the Meccans led by
Khalid bin Walid counterattacked and he continued to fight on until he was finally forced to retreat away from the Meccans. In fact, Sa'd was the last Muslim
Mus'ab ibn 'Umair met (Sa'd by that time had disengaged the Meccans) when he chided other Muslims for retreating and ferociously attacked the Meccans resulting in his brutal martyrdom at the hands of the Meccans. He later met up with Muhammad and was part of the small contingent Muslims defending him. Sa'd's brother 'Amr and his stepson (nephew) al-Harith ibn Aws were both among those who were killed at Uhud. Later the
Muslims laid siege to their stronghold and the Banu Qurayza surrendered. Several members of the
Banu Aws pleaded for their old Jewish allies and agreed to Muhammad's proposal that one of their chiefs should judge the matter. The Banu Qurayza themselves appointed Sa'd, and declared they would agree with whatever was Sa'd's verdict. The verdict for the Banu Qurayza, a Jewish clan in Medina, was consistent with the Old Testament and some scholars claim the verdict was based on Deutoronomy 20:12-14. ==Death==
