Which companion presented a specialized suit of armor (Zirah) to the Holy Prophet ﷺ during the Battle of Badr?

The Battle of Badr in 2 AH was marked by a severe lack of military equipment among the early Muslim defensive forces, requiring deep communal support from leading Ansar companions.

• During this encounter, Hazrat Sa'd bin Mu'adh (RA), the prominent chief of the Aus tribe of the Ansar in Madinah, presented a specialized suit of armor (Zirah) to the Holy Prophet ﷺ.
• This contribution underscored the absolute dedication of the Medinan leadership to protecting the Holy Prophet ﷺ during their initial, existential military conflicts.
