Buy food items when they are in good condition and safe to consume before purchasing them .

This hadith is about the sale of fruits and dates. It is narrated by Ibn Umar that Allah's Apostle forbade the sale of fruits until their good condition becomes evident, meaning that they should not be sold before they are ripe and ready to eat. He also forbade buying dates for other dates, meaning that one should not buy a certain type or quality of date with another type or quality. This hadith teaches us to be mindful when we buy food items, as we should only purchase them when they are in good condition and not exchange one item for another without considering its quality. We must also ensure that our food items are fresh and safe to consume before purchasing them.
