The Messenger of Allah ﷺ sent him out on a military expedition. Yala bin Muslim informed me of this from Saeed bin Jubayr, from Ibn Abbas.
حدثنا محمد بن يحيى النيسابوري حدثنا الحجاج بن محمد حدثنا ابن جريج في قوله {أطيعوا الله وأطيعوا الرسول وأولي الأمر منكم}
بعثه رسول الله ﷺ على سرية أخبرنيه يعلى بن مسلم عن سعيد بن جبير عن ابن عباس
Agreed upon. Bukhari narrated it in the Book of Tafsir, chapter, "Obey Allah and obey the Messenger and those in authority among you" [Nisa 4:59], and those of command, hadith no. 4584, and Muslim narrated it, hadith no. 1834, from the hadith of Hajjaj bin Muhammad, with similar wording.
