Musnad Ahmad

It is narrated from Sayyiduna Abdullah bin Ja'far (may Allah be pleased with him) that once the Prophet (peace and blessings of Allah be upon him) dispatched an army and appointed Sayyiduna Zaid bin Harithah (may Allah be pleased with him) as its commander. In case of his martyrdom, Sayyiduna Ja'far (may Allah be pleased with him) was to be the commander, and in case of his martyrdom, Sayyiduna Abdullah bin Rawahah (may Allah be pleased with him) was appointed as the commander. They confronted the enemy. Sayyiduna Zaid bin Harithah (may Allah be pleased with him) took the flag in his hand and fought so bravely that he was martyred. Then Sayyiduna Ja'far (may Allah be pleased with him) took the flag in his hand and began to fight, but he too was martyred. Then Sayyiduna Abdullah bin Rawahah (may Allah be pleased with him) took the flag in his hand and began to fight, but he too was martyred. Then Sayyiduna Khalid bin Walid (may Allah be pleased with him) took the flag in his hand, and Allah granted victory to the Muslims at his hand. When the Prophet (peace and blessings of Allah be upon him) received news of this incident, he came to the people, praised and glorified Allah, and said: "Your brothers confronted the enemy. Zaid (may Allah be pleased with him) took the flag and began to fight and was martyred. After him, Ja'far bin Abi Talib (may Allah be pleased with him) took the flag and began to fight and he too was martyred. Then Abdullah bin Rawahah (may Allah be pleased with him) took the flag and began to fight, but he too was martyred. After that, one of Allah's swords, Khalid bin Walid (may Allah be pleased with him), took the flag and began to fight, so Allah granted him victory." Then, three days later, the Prophet (peace and blessings of Allah be upon him) came to the family of Sayyiduna Ja'far (may Allah be pleased with him) and said: "Do not weep for my brother after today. Bring my two nephews to me." We were brought to the Prophet (peace and blessings of Allah be upon him), and at that time we were like chicks. The Prophet (peace and blessings of Allah be upon him) ordered a barber to be called, who came and shaved our heads. Then he said: "Of these, Muhammad resembles our uncle Abu Talib, and Abdullah resembles me in appearance and character." Then the Prophet (peace and blessings of Allah be upon him) took my hand, raised it, and prayed: «اَللّٰهُمَّ اخْلُفْ جَعْفَرًا فِي أَهْلِهِ وَبَارِكْ لِعَبْدِ اللّٰهِ فِي صَفْقَةِ يَمِينِهِ» "O Allah! Grant Ja'far's family a good substitute, and bless Abdullah's right hand." The Prophet (peace and blessings of Allah be upon him) made this supplication three times. Meanwhile, our mother also arrived and began to express her grief and our orphanhood. The Prophet (peace and blessings of Allah be upon him) said: "Do you fear poverty for them? I am their guardian in this world and the Hereafter."
