ʿAllāmah Ḥasan b. Tūrkhān al-Āqḥiṣārī’s (951-1025 AH) abridgment of ʿAbd Allāh b. Aḥmad al-Nasafī’s Manār al-Anwār fī Uṣūl al-Fiqh, entitled Samt al-Wuṣūl ilā ʿIlm al-Uṣūl, is considered by some to be the most excellent of al-Manār’s abridgments. While it may be useful to formally study on its own (or with a commentary), I believe that one clear use of this abridgment is for students of one of the commentaries of al-Manār, such as Mullā Jīwan’s Nūr al-Anwār, or al-Ḥaṣkafī’s Ifāḍat al-Anwār. Students of these larger works often lose track of the original text and find it hard to follow the outline provided by al-Nasafī. Given that al-Manār is occasionally cryptic or not as concise as one would want for the purposes of memorization, this work can serve as an excellent study guide and memorization tool.
I am uploading the pdf version that I found available online. This is not the edition published by Dār al-Iḥsān with the edits of ʿAlā ʿAbd al-Ḥamīd, but I have included a picture of the cover in case someone wants to print it along with the body of the text. I suggest students at Darul Qasim use this for review and memorization as they go through al-Ḥaṣkafī’s Ifāḍah.

What is a good commentary on Samt al-Wuṣūl ilā ʿIlm al-Uṣūl?
