Abdullah bin Umar reported,

In the expedition of Mutah, the Messenger of Allah ﷺ appointed Zayd bin Haritha as commander, and the Messenger of Allah ﷺ said, "If Zayd is killed, then Jafar will take command, and if Jafar is killed, then Abdullah bin Rawaha."Abdullah said, "I was among them in that expedition. We searched for Jafar bin Abu Talib and found him among the slain, and we found on his body more than ninety wounds from spear thrusts and arrows."
