This is the highly beneficial two volume work in explanation of the famous works by Imam al-Barbahari (d.329h) by the esteemed & noble Shaykh, Dr Saalih al- Fawzan. Its importance can be seen by virtue of its being compiled in the early times; as it is one of the books of the earliest Salaf - those who lived in the same period with the great Imams, acquired knowledge from them and reported their pure Aqeedah(creed).
