Usul al-Rashad (اصول الرشاد لمقع مبانی الفساد) by Mawlana Naqi Ali Khan (RA)
مصنف علامہ مولانا نقی علی خان (والد امام احمد رضا خان بریلوی)
Usul ar-Rashaad Li-Maq'a Mabani al-Fasaad
By Mawlana Naqi Ali Khan (father of Imam Ahmed Raza Khan)
This is a really valuable book in which the father of the great Imam, who himself was a leading scholar of the time, has discussed the problems with the Deobandi school of thought in light of the earlier scholars and their works. This is a masterpiece of later day Islamic theology.
