A horse of Ibn 'Umar fled and the enemy took it. Then the Muslims conquered the enemy and the horse was returned to him during the lifetime of Messenger of Allah ﷺ. And also, once a slave of Ibn 'Umar (ra) fled and joined the Byzantines, and when the Muslims conquered them, Khalid bin Al-Walid returned the slave to him after the death of the Prophet ﷺ.
