A "Weak Hadith" refers to a narration about the sayings or actions of the Prophet Muhammad that lacks sufficient authenticity. This can occur due to issues in the chain of transmission, such as unreliable narrators or missing links. Scholars assess the strength of hadiths to determine their reliability in Islamic teachings. Weak hadiths are generally not used as a basis for legal rulings or beliefs in Islam. However, they may still be considered for moral guidance or supplementary teachings, provided they do not contradict stronger hadiths or the core principles of the faith.
