What is Al-Tabarani's "Weak Chain" (al-Silsilah al-Da'ifah), and which of his books—Al-Mu'jam al-Saghir, al-Awsat, or al-Kabir—contains weak hadiths? Does the book that contains weak hadiths not include any authentic hadiths?

Al-Tabarani's dictionaries are three: Al-Mu'jam al-Saghir (The Small Lexicon), Al-Mu'jam al-Awsat (The Middle Lexicon), and Al-Mu'jam al-Kabir (The Great Lexicon). Al-Tabarani arranged them alphabetically according to the names of his teachers. His dictionaries include authentic (sahih), good (hasan), and weak (da'if) hadiths, and there is no such thing as "Al-Tabarani's Chain of Weak Hadiths" attributed to him.
