Mukhtasar al-Muntaha al-Usul Ibn Hajib

Imam Uthman Ibn al-Hajib al-Maliki's seminal text in Usul ul-Fiqh is one of the most commentated-upon and studied text in Usul ul-Fiqh across the world. It is studied by Malikis and non-Malikis alike, and even by Hanafis in the Indian subcontinent due to its condensed length filled with incredibly detailed meanings. It has commentaries by luminaries such as Imam Al-Taftazani, Al-Iji, and many, many more luminaries.
