Are all the Hadiths that "al-Durar al-Saniyyah" website has judged to be authentic (sahih) indeed authentic? And is it permissible to disseminate Hadiths that have been judged as "hasan" (good), "sahih al-isnad" (authentic in chain of narration), or "rijaluhu thiqat" (its narrators are trustworthy)?

The "Durar Saniyyah" website is one of the distinguished Islamic websites. The website located at http://hdith.com is a hadith-related website that relies on "Durar Saniyyah" for verifying the grades of hadiths. The "Durar Saniyyah" website transmits the words of the scholars of Hadith, who may differ in authenticating and weakening hadiths. The hadiths published on "Durar Saniyyah" are of three types: the first type is what has been transmitted through numerous narrations as authentic; the second type is what has been transmitted through numerous narrations as weak or fabricated; and the third type is what appears to be a matter of ijtihad (independent juristic reasoning) regarding its authenticity or weakness. The phrase "its narrators are trustworthy" does not necessarily mean the hadith is authentic, as its chain of narration may be interrupted (munqati‘), defective (ma‘lul), or anomalous (shadhdh), as clarified by Al-Albani.
