Narrated 'Abdur-Rahman bin Abza and 'Abdullah bin Abu Aufa (RA):

"We were getting a portion of the spoils of war along with Allah's Messenger (ﷺ), and some Nabateans (Arabs who mixed with non-Arabs and corrupted their language and lineage) from those of Syria used to come to us and we would pay in advance to them for wheat, barley and raisins - A narration has: 'and olive oil' - for a specified fixed time." It was asked, "Did they have standing crop?" They replied, "We were not asking them about that." [Reported by al-Bukhari].
