Awf bin Malik reported,

I went out with Zayd bin Haritha among the Muslims who set out on the expedition of Mutah. A reinforcement fighter from Yemen accompanied me, and he had nothing with him except his sword.A man from the Muslims slaughtered a camel, and the Yemeni asked him for a portion of its hide, which he gave to him. He fashioned it into something resembling a shield, and we proceeded onward.We met the Roman forces, among whom was a man on a chestnut horse, with a gilded saddle and gilded weapons. This Roman began harassing the Muslims, so the Yemeni took position for him behind a rock. When the Roman passed by, he hamstrung his horse, and it collapsed. He then leapt upon him and killed him, taking possession of his horse and weapons.When Allah granted victory to the Muslims, Khalid bin Walid sent for him and took the spoils from him.Awf said, "I came to him and said, 'Khalid, do you not know that the Messenger of Allah ﷺ has ruled that the spoils belong to the killer?'"Khalid replied, "Yes, but I considered it too much."I said, "You shall return it to him, or I will surely report this to the Messenger of Allah ﷺ."But he refused to return it.Awf said, "We then came together before the Messenger of Allah ﷺ, and I told him the story of the Yemeni and what Khalid had done."The Messenger of Allah ﷺ said, "Khalid, what made you do what you did?"Khalid said, "Messenger of Allah, I considered it too much."The Messenger of Allah ﷺ said, "Khalid, return to him what you took from him."Awf said, "I said to Khalid, 'Take that, Khalid! Did I not fulfill my word to you?'"The Messenger of Allah ﷺ asked, "What is this?"So I informed him, and the Messenger of Allah became angry and said, "Khalid, do not return it to him. Will you not leave my commanders alone for my sake? You get the best of their leadership, and they bear its hardships."Walid said, "I asked Thawr about this hadith, and he related it to me from Khalid bin Madan, from Jubayr bin Nufayr, from Awf bin Malik al-Ashjai, in similar terms."

حدثنا الوليد بن مسلم قال حدثني صفوان بن عمرو عن عبد الرحمن بن جبير بن نفير عن أبيه

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 فاجتمعا عند رسول الله ﷺ وقصصت عليه قصة المددي وما فعله 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 فقال دونك يا خالد ألم أف لك فقال رسول الله ﷺ وما ذاك فأخبرته فغضب رسول الله وقال يا خالد لا ترده عليه هل أنتم تاركو إلي 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
