Al-Wadhih fi Usul al-Fiqh by Ibn 'Aqil al-Hanbali - 5 volumes

Al-Wadih fi Usul Al-Fiqh (The Clear Book in the Fundamentals of Jurisprudence) is writtten by Imam Ibn Aqil al-Hanbali (531H).

This book is rightfully considered one of the main books of Usul in general, and Usul Al-Hanbali in particular, in which the author followed the process of investigation in listing the statements, the opinions and their objections, in discussing them and deducing what he sees as preponderant with jurisprudential evidence, in an easy and clear style. This edition has been carefully investigated and has scientific comments.

Very fine edition with the Tahqiq of Abdullah at-Turki, verified from a manuscript, with the harakat in part.
