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. (Using translation from Bukhārī 3067)
ذَهَبَتْ لَهُ فَرَسٌ فَأَخَذَهَا الْعَدُوُّ فَظَهَرَ عَلَيْهِمُ الْمُسْلِمُونَ فَرُدَّتْ عَلَيْهِ فِي زَمَنِ رَسُولِ اللهِ ﷺ قَالَ وَأَبَقَ عَبْدٌ لَهُ فَلَحِقَ بِالرُّومِ فَظَهَرَ عَلَيْهِ الْمُسْلِمُونَ فَرَدَّهُ عَلَيْهِ خَالِدُ بْنُ الْوَلِيدِ بَعْدَ النَّبِيِّ ﷺ
