I saw that during the time of the Messenger of Allah (ﷺ) the people were beaten when they bought grain on the same spot and sold it there without moving it to their houses.
Sunan Abi Dawud Book 24, Hadith 83
← Previous Hadith The Messenger of Allah (ﷺ) as saying: If anyone buys a grain, he should not sell it until he takes possession of it. Sulaiman b. Harb said: Until he receives it in full. Musaddad added: Ibn 'Abbas said: And I think that everything is like grain.

Sunan Abi Dawud Book 24, Hadith 82 Next Hadith → I bought olive oil in the market. When I became its owner, a man met me and offered good profit for it. I intended to settle the bargain with him, but a man caught hold of my hand from behind. When I turned I found that he was Zayd ibn Thabit. He said: Do not sell it on the spot where you have bought it until you take it to your house, for the Messenger of Allah (ﷺ) forbade to sell the goods where they are bought until the tradesmen take them to their houses.
