Iyas bin Salama reported,

I went on a campaign with the Messenger of Allah ﷺ against the tribe of Hawazin.He said, while we were eating our morning meal, with most of us on foot and some weak ones among us, a man came riding on a red camel. He pulled out a leather cord from his belt and tethered his camel with it. He was a young man. Then he came and ate breakfast with the people. When he saw their weakness and the poor condition of their mounts, he went out to his camel, untied it, made it kneel, mounted it, and rode off at a gallop.A man from the tribe of Aslam, one of the companions of the Prophet ﷺ, pursued him on a grey she-camel that was the best of the people's mounts. He chased after him.He said, I set out running and caught up with him. The head of the she-camel was at the flank of the camel, and I was at the flank of the she-camel. Then I advanced until I was at the flank of the camel, then I advanced further until I grabbed the camel's halter and made it kneel. When it placed its knee on the ground, I drew my sword and struck him on the head, and his head flew off. Then I came leading his mount with all that was on it.The Messenger of Allah ﷺ met me as he was approaching and asked, "Who killed the man?"They said, "Ibn al-Akwa."He said, "He gets all of his spoils."

Sahih

قال هاشم بن القاسم قال حدثنا عكرمة قال

حدثني إياس بن سلمة بن الأكوع قال حدثني أبي قال

غزوت مع رسول الله ﷺ هوازن قال فبينما نحن نتضحى وعامتنا مشاة فينا ضعفة إذ جاء رجل على جمل أحمر فانتزع طلقا عن حقبه فقيد به جمله رجل شاب ثم جاء يتغدى مع القوم فلما رأى ضعفهم ورقة ظهرهم خرج إلى جمله فأطلقه ثم أناخه فقعد عليه فخرج يركض وتبعه رجل من أسلم من صحابة النبي ﷺ على ناقة ورقاء هي أمثل ظهر القوم فأتبعه قال وخرجت أعدو فأدركته ورأس الناقة عند ورك الجمل وكنت عند ورك الناقة ثم تقدمت حتى كنت عند ورك الجمل ثم تقدمت حتى أخذت بخطام الجمل فأنخته فلما وضع ركبته إلى الأرض اخترطت سيفي فأضرب به رأسه فندر فجئت براحلته وما عليها أقوده فاستقبلني رسول الله ﷺ مقبلا قال من قتل الرجل قالوا ابن الأكوع قال له سلبه أجمع
