It was narrated that 'Ala' bin Hadrami said: "The Messenger of Allah P.B.U.H sent me to Bahrain or Hajar. I used to go to a garden that was shared by some brothers, one of whom had become Muslim. I would take the 'Ushr (one-tenth of the harvest) from the Muslim, and the Kharilj from the Mushrik." (Da'if)
