لسان الميزان

By Ibn Hajar al-Asqalani 852h (1448 CE) 8 volumes

A reworking of al-Dhahabi's Mizan al-I'tidal focused on weak and discredited hadith narrators. Ibn Hajar adds corrections, additional information, and narrators that al-Dhahabi missed, creating the most complete reference for weak narrators.
