"Messenger of Allah ﷺ appointed Zaid bin Haritha as the commander of the army during the Ghazwa of Mu'tah and said, "If Zaid is martyred, Jaʿfar should take over his position, and if Jaʿfar is martyred, ʿAbdullah bin Rawaha should take over his position.' " ʿAbdulla-h bin ʿUmar further said, "I was present amongst them in that battle and we searched for Jaʿfar bin Abi Talib and found his body amongst the bodies of the martyred ones, and found over ninety wounds over his body, caused by stabs or shots (of arrows).
أَمَّرَ رَسُولُ اللَّهِ ﷺ فِي غَزْوَةِ مُوتَةَ زَيْدَ بْنَ حَارِثَةَ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنْ قُتِلَ زَيْدٌ فَجَعْفَرٌ وَإِنْ قُتِلَ جَعْفَرٌ فَعَبْدُ اللَّهِ بْنُ رَوَاحَةَ قَالَ عَبْدُ اللَّهِ كُنْتُ فِيهِمْ فِي تِلْكَ الْغَزْوَةِ فَالْتَمَسْنَا جَعْفَرَ بْنَ أَبِي طَالِبٍ فَوَجَدْنَاهُ فِي الْقَتْلَى وَوَجَدْنَا مَا فِي جَسَدِهِ بِضْعًا وَتِسْعِينَ مِنْ طَعْنَةٍ وَرَمْيَةٍ
