Nihayat Sul fi Sharh Minhaj al-Wusul - Imam Al-Isnawi

This explanation is among the most famous and most appreciated of Matn Minhaj al-Wusul ila 'Ilm al-Usul of Imam al-Baydawi. Appreciated because of the great eloquence and mastery of the Arabic language of its author and its profound mastery of the text in question of the science of Usul al-Fiqh.

The author is Imam Jamal ad-Din al-Isnawi (772H), whose merit can be illustrated by mentioning his Shuyukh (ibn al-'Athir, Taqi ad-Din as-Subki, Ibn Hayyan) and his pupils (Ibn al-Mulaqqin, Az-Zarkachi, al-Hafidh al-'Iraqi), rahimahum Allah.

Very good edition in 2 volumes, with authentication and annotations.
