Distribution of his Wealth as Inheritance
Hazrat Zubair (ra) had four wives; he had divided one eighth, i.e., the portion allotted to one’s wife [from the inheritance], into four parts. Thus, each wife received 1.1 million (when the remaining property was distributed, each wife received 1.1 million). According to one narration, his total wealth amounted to 35.2 million. Sufyan bin Uyaynah narrates that the inheritance of Hazrat Zubair (ra) which was distributed was 40 million.
Hisham bin Urwah narrates on the authority of his father that the total amount left behind by Hazrat Zubair (ra) was approximately 51 to 52 million. Similarly, Urwah relates that Hazrat Zubair (ra) owned land in Egypt, including Alexandria. He also owned land in Kufa and some houses in Basra. He received an income from his properties in Medina.

Nonetheless, after all his debt was cleared, the remaining wealth was distributed amongst his heirs.
