Returning lost items or possessions no matter who owns them

This hadith speaks to the importance of returning lost items to their rightful owners, even if they are enemies. It is narrated by Nafi' that a horse belonging to Ibn 'Umar fled and was taken by the enemy. When the Muslims conquered them, Khalid bin Al-Walid returned it back to him during the lifetime of Allah's Messenger. Similarly, a slave belonging to Ibn 'Umar also fled and joined the Byzantines but when Muslims conquered them, Khalid bin Al-Walid returned him back after Prophet Muhammad's death. This hadith teaches us that we should always return lost items or possessions no matter who owns them as it is an act of righteousness and justice in Islam. We should not take advantage of someone else’s misfortune or loss and instead help them out in any way we can so that they can get back what belongs to them.
