He is known as Al-Quduri because he was born in a place called Qudurah which was located on the outskirts of Baghdad. The actual date of his birth is not known.

Among all his works, Al-Quduri is the most famous work which is used as a textbook of Fiqh Al-Hanafi all over the world. It contains about 12,500 issues of Fiqh.
Imam Badruddin Al-Aini wrote that when Imam Quduri finished writing Al-Quduri, he went on Hajj and took this book along with him. After completing the Tawaf, he supplicated to Allah to help him identify and rectify the errors in his book. After the Hajj, he went through his book in detail, page by page, and it was reported that he found only six places where some editing was required.
Many commentaries have been written on Al-Quduri which include, Al-Jawharah Al-Nayyirah and Zad al-Fuqaha.
