Sharh 'Ilal at-Tirmidhi li Ibn Rajab (2 vol.)

Sharh 'Ilal at-Tirmidhi of Haafidh Ibn Rajab al-Hanbali is an important and indispensable book in the science of hadith and its terminology, specifically the science of 'Ilal (abnormalities faults), and besides Shaykh Muhammad Bazmoul considers it the best in this matter.

Very good edition in two volumes, scrupulously checked and richly annotated.
