Awf bin Malik reported,

Awf bin Malik reported, "I went out with the Muslims who joined Zayd bin Haritha on the expedition of Mutah. A reinforcement fighter from Yemen accompanied me, carrying nothing but his sword. One of the Muslims slaughtered a camel, and the Yemeni man asked him for a piece of its hide. The man gave it to him, and he fashioned it into something like a small shield.We continued on and met the Byzantine forces. Among them was a man on a chestnut horse, with a gilded saddle and gilded weapons. This Byzantine fighter began harassing the Muslims. The Yemeni reinforcement lay in wait for him behind a rock, and when the Byzantine passed by, he hamstrung his horse. The man fell, and the Yemeni pounced on him and killed him, then took possession of his horse and weapons.When Allah granted the Muslims victory, Khalid bin Walid sent for him and took the spoils from him."Awf continued, "I went to Khalid and said, 'Khalid, do you not know that the Messenger of Allah ﷺ ruled that the spoils belong to the killer?'He replied, 'Yes, but I considered it too much for him.'I said, 'You will return it to him, or I will surely make this known to the Messenger of Allah ﷺ.'But he refused to return it."Awf continued, "We then gathered before the Messenger of Allah ﷺ, and I told him the story of the Yemeni reinforcement and what Khalid had done.The Messenger of Allah ﷺ said, 'Khalid, what made you do what you did?'He answered, 'Messenger of Allah, I considered it too much for him.'The Messenger of Allah ﷺ said, 'Khalid, return to him what you took from him.'"Awf continued, "I said, 'There you go, Khalid. Did I not make good on my word to you?'The Messenger of Allah ﷺ asked, 'What is this?'So I informed him. The Messenger of Allah ﷺ became angry and said, 'Khalid, do not return it to him. Will you not leave my commanders alone for me? You get the choicest part of their service, while they bear its burdens.'"Walid said, "I asked Thawr about this hadith, and he narrated it to me from Khalid bin Madan, from Jubayr bin Nufayr, from Awf bin Malik al-Ashjai, in similar wording."

عن عوف بن مالك الأشجعي قال

خرجت مع من خرج مع زيد بن حارثة من المسلمين في غزوة مؤتة، ورافقني مددي من اليمن ليس معه غير سيفه، فنحر رجل من المسلمين جزورا، فسأله المددي طائفة من جلده فأعطاه إياه، فاتخذه كهيئة الدرق، ومضينا فلقينا جموع الروم، وفيهم رجل على فرس له أشقر، عليه سرج مذهب، وسلاح مذهب، فجعل الرومي يغري بالمسلمين، وقعد له المددي خلف صخرة فمر به الرومي، فعرقب فرسه، فخر وعلاه فقتله، وحاز فرسه وسلاحه، فلما فتح الله للمسلمين بعث إليه خالد بن الوليد فأخذ منه السلب قال عوف: فأتيته فقلت: يا خالد، أما علمت أن رسول الله ﷺ قضى بالسلب للقاتل؟ قال: بلى ولكني استكثرته قلت: لتردنه إليه أو لأعرفنكها عند رسول الله ﷺ، وأبى أن يرد عليه، قال عوف: فاجتمعنا عند رسول الله ﷺ فقصصت عليه قصة المددي ومافعله خالد، فقال رسول الله ﷺ: يا خالد، ما حملك على ما صنعت؟ قال يا رسول الله ﷺ استكثرته. فقال رسول الله ﷺ: يا خالد رد عليه ما أخذت منه قال عوف: فقلت: دونك يا خالد ألم أف لك؟ فقال رسول الله ﷺ: وما ذاك؟ فأخبرته، فغضب رسول الله ﷺ، وقال: يا خالد لاترده عليه هل أنتم تاركو لي أمرائي لكم صفوة أمرهم وعليهم كدره. قال الوليد: سألت ثورا عن هذا الحديث، فحدثني عن خالد بن معدان، عن جبير بن نفير، عن عوف بن مالك الأشجعي، نحوه.
