The eminent scholar, Abū al-Qāsim al-Baghdādī al-Karkhī, a Shāfiʿī jurist.
Abū Isḥāq mentions him in “Ṭabaqāt al-Fuqahāʾ,” saying: “Among them is our shaykh Abū al-Qāsim al-Karkhī. He studied under Abū Ḥāmid al-Isfarāʾīnī, possesses a set of his notes, composed within the school the book al-Ghunya (2), and taught in Baghdad.”

It refers to a small town at the far border of the Iraqi province, marking the frontier between the districts of Shahrzur and Iraq (Muʿjam al-buldan 4/449).
