فتاوى شيخ الاسلام ابي الحسن عطاء بن حمزة السغدي

A very rare, early Hanafi work, printed using the only manuscript the muhaqqiq could find.

It is the fatawa of Allamah Ata ibn Hamzah as-Sughdi, gathered by his student Najd ad-Din an-Nasafi (d. 537AH). Most fuqaha didn't have access to it, with just a few quotes from it found in classical works
