'Abdullah bin 'Umar said: "The Messenger of Allah stood up among us ad said: 'Do not sell fruits until their condition is known"".
This hadith also teaches us about being patient when dealing with others, especially when trading goods or services. We should take our time to make sure everything is as expected before going ahead with a transaction, so as to avoid any misunderstandings or disputes later on down the line. It also encourages us to be mindful of our actions and how they may affect others, as well as ourselves in the long run.
