As-Salaam alaikum,
In Ayat 7 of Surat Hashar of the Holy Qur'an (59:7), Allah, Subhanahu Wa Ta'ala, says:--

"Whatever gains Allah turns over to His Messenger from the people of the
townships belong to Allah, the Messenger, Kinsfolk, Orphans, the Needy
and the Traveller in need. Thus they would not just circulate money among
those of you who are rich."

This Ayat states a major rule of the Muslim Ummah's economic and social system-- that money "would not just circulate among those of you who are rich". Although this rule is stated in connection with the gains made in a particular encounter, it goes beyond the immediate event to state fundamental principle for the Islamic social system.

Islamic economic system approves private ownership but makes it subject to this rule.... that excludes the possibility of wealth being circulated only among the rich in society. And Islam strictly forbids monopoly and usury, which are the 2 main tools leading to money being circulated purely among the rich.
