This is what I have found on this topic.

"I came to the Prophet and said: 'Wait, I want to ask you something. I sell camels in Al-Baqi with a price set in Dinars but I accept Dirhams instead.' He said: 'There is nothing wrong with it if you take the price on that day, still unfinished business between you both (buyer and seller)"'

"When the Prophet (ﷺ) came to Al-Madinah, he called for a scale and weighed (something) for me and gave me more."

'The Messenger of Allah paid off what he owed me, and gave me more."

"Makhrafah Al-Abdi and I brought some cloth from Hajar, and the Messenger of Allah came to us while we were in Mina where there w a man who weighed (goods) in return for payment. He bought some trousers from us, and said to the man who weighed: 'Weigh it, and allow more."'

"I heard Abu Safwan say: 'I bought a pair of trousers from the Messenger of Allah before the Hijrah, and he weighed it for me and allowed me."'

"The Messenger of Allah said: "Volume is to be measured according to the system of the people of Al-Madinah, and weight is to be measured according to the system of the peole of Makkah."' (Sahih) This is the wording of Ishaq (one of the narrators).

"The Messenger of Allah said: 'Whoever buys food, let him not sell it until he has taken possession of it."'

"Whoever buys food let him not sell it until he has taken possession of it."

"The Messenger of Allah said: 'Whoever buys food, let him not sell it until he has checked its weight.""

"I heard the Prophet say" something similar to the preceding two reports "until he takes possession of it."

"I heard Ibn 'Abbas say: 'As for that which the Messenger of Allah forbade, (it is) selling before taking possession of food."'

"The Messenger of Allah said: 'Whoever buys food let him not sell it until he takes possession of it. Ibn 'Abbas said: "I think the same applies to everything else as to food."

"The Messenger of Allah said: "Do not sell food until you have bought it and taken possession of it."'

"Ata' told me that from 'Abdullah bin 'Ismah Al-Jushami from Hakim bin Hizam from the prophet. "

"I bought some food and made food and made a profit on it (by selling it) before I took possession of it. I came to the Messenger of Allah and told him about that and he said: 'Do not sell it until you take possession of it."'

the Prophet forbade anyone to sell food that he brought

"During the time the Messenger of Allah we used to buy food, and he sent someone to tell us to remove it from the place where we had bought it, to another place, b before selling"

they used to buy and sell during the time of the Messenger of Allah at the top of the marketplace without measuring. The Messenger of Allah forbade them to sell it in the place where they had bought it until they moved it.

they used to buy foold from the riders at the time of the Messenger of Allah and he forbade them to sell it in the place where they had bought it until they moved it to the food market.
