The Messenger of Allah (ﷺ) forbade to sell grain which one buys by measurement until one receives it in full.
Sunan Abi Dawud Book 24, Hadith 80
← Previous Hadith They (the people) used to buy grain in the upper part of the market in the same spot without measuring or weighing it. The Messenger of Allah (ﷺ) forbade them to sell it there before removing it.

Sunan Abi Dawud Book 24, Hadith 79 Next Hadith → The Messenger of Allah (ﷺ) as saying: If anyone buys grain, he should not sell it until he measures it. Abu Bakr added in his version: I asked Ibn 'Abbas: Why ? He replied: Do you not see that they sell (grain) for gold, but the grain is still with the seller.
