Make promises you can keep; If you break your promise/oath then perform kaffarah; Follow the teachings and practices of Prophet Muhammad (ﷺ) .

This hadith reminds us that if we break an oath, we must make expiation for it. An oath is a promise or commitment made to God or another person, and breaking it is considered a sin in Islam. To make up for this sin, one must perform an act of expiation known as Kaffara. This could include fasting for two consecutive days or feeding ten poor people with the same amount of food they would normally eat in one day. Additionally, the hadith also mentions Sunnah which refers to the teachings and practices of Prophet Muhammad ﷺ which Muslims should follow as examples in their lives.
