Wait until your produce has been harvested before selling it

The hadith narrated by Ibn 'umar states that Prophet Muhammad forbade a certain practice known as Muzabanah. This refers to when a person sells their produce such as dates, grapes, or grain while they are still on the trees, vines, or in the field. This means that they would estimate how much produce was there and then sell it for a measure of dry dates or raisins instead. Prophet Muhammad forbid this practice and encouraged people to wait until their produce was harvested before selling it. This teaches us to be patient and not rush into things without thinking them through properly first. It also teaches us to be honest in our dealings with others and not try to take advantage of them by estimating an amount that is higher than what is actually there.
