In Jami'Al-Usül, 51 Ibn Al-AthIr said: "(It) is the best of the books, 16 having the most benefit, the best organization, with the least repetition. It contains what others do not contain; like mention of the different Madhhabs (views), angles of argument, and clarifying the circumstances of the Hadith being authentic, weak, Gharib (odd), as well as disparaging and endorsing remarks (regarding narrators).
