Follow prescribed punishments according to Islamic law.

This hadith speaks about the proper way to deal with non-believers according to Islamic law. It tells us that it is not permissible for Muslims to punish non-believers by using Allah's punishment, such as fire. Instead, they should use other forms of punishment such as killing them according to the statement of Allah's Messenger. The main idea behind this is that Muslims should not take matters into their own hands and instead follow what has been prescribed in Islam for dealing with non-believers. This teaches us that we must always abide by the laws set forth in Islam and not take matters into our own hands when dealing with those who do not believe in our faith.
