(Some part is due) to the indigent Muhajirs, those who were expelled from their homes and their property, while seeking Grace from Allah and (His) Good Pleasure, and aiding Allah and His Messenger: such are indeed the sincere ones:- Al-Hashr 59:8 ⧉
Tafsir:
When the enemy have fled after defeat, their possessions are considered spoils of war (ghanimah). Sometimes the enemy retreats without fighting. On such occasions the booty acquired is described as abandoned property (fay’). As for the spoils of war, after a fifth part has been taken out, all of the remaining portion is the share of the army. While all the abandoned property in the case of Fay belongs to the Islamic government and is to be spent in the public interest. It is the intention of Islam that wealth should not remain restricted to a particular class but should reach every class. In Islam, there is no concept of economy controlled by the State. However, its economic rules are so framed that wealth should not be concentrated, but should keep circulating in all groups.
