Have proper documentation or witnesses when entering into a marriage contract .

This hadith is about the importance of having proof before getting married. It warns against committing adultery which is a major sin in Islam. The Prophet Muhammad ﷺ said that adulteresses are those who marry themselves without any proof or evidence. This means that couples should not get married without proper documentation or witnesses to prove their marriage contract. It also implies that couples should not engage in any kind of sexual activity outside marriage as it is considered a major sin in Islam and can lead to serious consequences both spiritually and socially. Therefore, it is important for couples to ensure they have all the necessary documents and witnesses when entering into a marriage contract so as to avoid any potential problems later on down the line.
