Measure or estimate fruits before buying or selling them according to Islamic law

This hadith discusses the Islamic law regarding selling fruits. The Prophet Muhammad ﷺ forbade Muzabana, which is the selling of fresh fruit without measuring it for something by measure. If what was measured turns out to be more than the fruit, then that increase would be for the seller of the fruit and if it turns out to be less, then that would be his lot. However, he allowed for people to sell fruits on trees after estimation when they are ripe. This means that people can estimate how much a certain amount of fruit will cost before buying or selling them in order to ensure fairness in transactions between buyers and sellers.
