Al-Jawāb as-Sahīh li-man baddala dīn al-Masīh - Ibn Taimiya - (6/158)

In Sahih al-Bukhari it is related:

“When the Prophet ﷺ dispatched the army for the expedition of Muʾtah, he placed Zayd ibn Ḥarithah in command and said, ‘If he is killed, then Jaʿfar (will lead); if he is killed, then ʿAbd Allah ibn Rawāḥah.’

Al-Bukhari transmits—on the authority of Anas ibn Mālik—that the Messenger of Allah ﷺ announced to the people the deaths of Zayd, Jaʿfar, and Ibn Rawāḥah before any news of them had reached Medina. He said, ‘Zayd took the standard and was struck down; then Jaʿfar took it and was struck down; then ʿAbd Allah ibn Rawāḥah took it and was struck down,’ while the eyes of the Messenger of Allah ﷺ were streaming with tears. ‘Then Khalid ibn al-Walid took it— a sword from among the swords of Allah—until Allah granted them victory.’"

وَفِي صَحِيحِ الْبُخَارِيِّ «لَمَّا أَرْسَلَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْجَيْشَ فِي غَزْوَةِ مُؤْتَةَ، وَأَمَّرَ عَلَيْهِمْ زَيْدَ بْنَ حَارِثَةَ، وَقَالَ إِنْ قُتِلَ فَجَعْفَرٌ فَإِنْ قُتِلَ فَعَبْدُ اللَّهِ بْنُ رَوَاحَةَ. فَرَوَى الْبُخَارِيُّ، عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ: نَعَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ زَيْدًا، وَجَعْفَرًا، وَابْنَ رَوَاحَةَ لِلنَّاسِ قَبْلَ أَنْ يَأْتِيَهُمْ خَبَرُهُمْ، فَقَالَ: أَخَذَ الرَّايَةَ زَيْدٌ فَأُصِيبَ، ثُمَّ أَخَذَهَا جَعْفَرٌ فَأُصِيبَ، ثُمَّ أَخَذَهَا عَبْدُ اللَّهِ بْنُ رَوَاحَةَ فَأُصِيبَ، وَإِنَّ عَيْنَيْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَتَذْرِفَانِ، ثُمَّ أَخَذَهَا خَالِدُ بْنُ الْوَلِيدِ سَيْفٌ مِنْ سُيُوفِ اللَّهِ، حَتَّى فَتَحَ اللَّهُ عَلَيْهِمْ» .
