(45) باب بَعْثُ النَّبِيِّ صلى الله عليه وسلم أُسَامَةَ بْنَ زَيْدٍ إِلَى الْحُرَقَاتِ مِنْ جُهَيْنَةَ
Narrated Salama bin Al-Akwa`:
I fought in seven Ghazwat (i.e. battles) along with the Prophet (ﷺ) and fought in nine battles, fought by armies dispatched by the Prophet. Once Abu Bakr was our commander and at another time, Usama was our commander.
