فضل علم السلف على علم الخلف
للإمام الحافظ بن رجب الحنبلي
Very good risâla by Imam Ibn Rajab Al-Hanbali which has the title: "Virtue of The Knowledge of The Salaf Over That of Khalaf".
The imam defines what religious science is and explains that it is of two kinds: beneficial knowledge and non-beneficial knowledge. Finally, he demonstrates the merit of pious predecessors' knowledge compared to that of those who came after them.
Very nice edition, the text of which has been transcribed from a very old Indian edition dating back over 140 years.
128 pages, yellow pages, 14x20 cm format, semi-rigid cover, دار القبس edition.
