Chapter 20: Tribute, Spoils, and Rulership (Kitab Al-Kharaj, Wal-Fai' Wal-Imarah)

Narrated Ibn al-Sa' idi: 'Umar reported me to collect the sadaqah (i. e. zakat). When I became free, he ordered to give me payment for it. I said: I have worked for the sake of Allah. He said: Take what you have been given, for I held an administrative post in the time of the Messenger of Allah (ﷺ), and he gave me payment for it.
Sunan Abi Dawud 2944
