Be wise when it comes to selling possessions or properties; Be honest in dealings with others; Think carefully about how much something is worth before making decisions on its sale; Do not take advantage of people who may not know better than you.

This hadith is about the Prophet Muhammad's advice to the Bani Najjar tribe. He asked them to suggest a price for their garden, which contained some date palms and a ruin. This hadith teaches us that we should be wise when it comes to selling our possessions or properties. We should not sell them at any cost but rather think carefully about how much they are worth and what kind of profit we can make from them. It also teaches us that we should be honest in our dealings with others and not take advantage of people who may not know better than us.
