Paying zakat on one's wealth as an obligation .

This hadith is about the obligation of paying zakat, which is a form of taxation, on wealth. According to this hadith, the Prophet Muhammad said that there is nothing due on wealth other than zakat. This means that if someone has wealth, they must pay a certain percentage as zakat in order to fulfill their religious obligations and help those in need. It also teaches us that we should not hoard our wealth but instead use it to help others who are less fortunate than us.
