This hadith emphasizes that any religious actions or innovations that are not supported by the Quran and authentic Sunnah will be rejected. While intentions are important, actions must also be carried out according to Islamic guidelines. Worship acts require explicit evidence from sacred sources, while general matters like dress and food are permissible unless explicitly prohibited. There is debate around the concept of "good innovations", with some scholars like Ash-Shafi'i arguing innovations can be acceptable if consistent with Islamic principles and not meant to exaggerate worship.
