The Fiqh Views that Abu Hanifa and the Companions have returned to

This is a very good research book that deals with the Fiqh Opinions that Abu Hanifah or his Companions among the Mujtahidūn Imams have returned to. The first part introduces the reversal of his opinions and the reasons for it in the Hanafi Fiqh, then the book sets out in the order of the Fiqh chapters the different opinions for which one or more Imams reversed by changing their opinion. The footnotes provide a comprehensive bibliography for the student who wants to go further and/or return to the sources.
