Narrated Umar ibn al-Khattab: A son of Adi ibn Adi al-Kindi said that Umar ibn Abdul Aziz wrote (to his governors): If anyone asks about the places where spoils (fay) should be spent, that should be done in accordance with the decision made by Umar ibn al-Khattab (Allah be pleased with him). The believers considered him to be just, according to the saying of the Prophet ﷺ: Allah has placed truth upon Umar's tongue and heart. He fixed stipends for Muslims, and provided protection for the people of other religions by levying jizyah (poll-tax) on them, deducting no fifth from it, nor taking it as booty.

Narrated Abu Dharr: I heard the Messenger of Allah ﷺ say: Allah, the Exalted, has placed truth on Umar's tongue and he speaks it.
