عمر بن عبد العزيز
When Umar ibn Abd al-Aziz, known as Umar II, became Caliph in 717 CE, the income from the property of Fadak was 40,000 dinars. Fadak was returned to Fatima's descendants by an edict given by Umar II, but this decision was renounced by later caliphs.Umar II's successor, Yazid ibn Abd al-Malik (known as Yazid II) overturned his decision, and Fadak was again made public trust. Fadak was then managed this way until the Ummayad Caliphate expired.
