The results of this study reveal several findings about the consistency of Hasbi Ash- Shiddieqy regarding the authenticity of hadith, namely: (1) Hasbi Ash-Shiddieqy's attitude towards daif hadith, seen Hasbi's inconsistency between theory and practice of using daif hadith. (2) The daif traditions in An-Nur's interpretation are generally not used as evidence in interpreting a verse, especially law verses, because the traditions are presented only as
explaining asbabul nuzul ayat, additional information in interpreting a verse. (3) The implication of the inclusion of daif hadith in An-Nur's interpretation has several forms,
namely Hasbi uses the dha'if traditions in An-Nur's Tafsir, even uses mawdhu 'hadiths or narrations that have mawdhu characteristics, then regarding how to quote the hadith which Without explaining the mukharij or the companions who narrated the hadith, to make matters worse Hasbi included the hadith with the Indonesian editorial staff, even without
including the mukharij or the narrators of the hadith, the inconsistency also for Hasbi was the use of hadith source books not from hadith books. Therefore, it is necessary to refill the hadiths in the Tafsir An-Nur book.
