Keep your promises and fulfill your obligations even if it means making sacrifices or going out of your way. Be mindful of how your actions can affect others and try to do what is best for them in any given situation.

This hadith is about the importance of keeping one's promises. In this hadith, a man made a promise to free his slave after he passed away, but since he did not have any other property besides the slave, the Prophet advised him to sell it instead. This teaches us that we should always keep our promises and fulfill our obligations even if it means making sacrifices or going out of our way. We should also be mindful of how our actions can affect others and try to do what is best for them in any given situation.
