This hadith emphasizes the importance of praying with an Imam. It teaches us that if we join in a prayer led by an Imam, it is as if we have prayed the entire prayer ourselves. This hadith encourages us to pray together in congregation and not miss out on any part of our prayers. It also reminds us that when we are praying alone, it is important to make sure that we complete all parts of our prayers and do not miss any rak’ahs or other components.
