Appoint leaders in times of war; Fight bravely for your faith; Be loyal and faithful; Step up when needed

This hadith is about the Prophet Muhammad's appointment of Zaid bin Haritha as commander of an army during a battle known as Ghazwa Mu'tah. The Prophet also gave instructions that if Zaid were to be martyred then Ja'far should take over his position and if Ja'far was martyred then 'Abdullah bin Rawaha should take over his position. Abdullah bin Umar was present at this battle and reported that they found Ja'far's body amongst those who had been martyred with ninety wounds from stabs or arrows on it. This hadith teaches us about the importance of appointing a leader in times of war and having someone ready to step up in case something happens to them. It also shows us how bravely these companions fought for their faith even when faced with certain death.
