Jawab al-qadi Abu l-Walid al-Baji ila risalat rahib Faransa ila al-Muslimin

The Jawāb al-qāḍī Abū l-Walīd al-Bājī ilā risālat rāhib Faransā ilā al-Muslimīn ('Reply of the Qāḍī Abū l-Walīd al-Bājī to the Letter of the Monk of France to the Muslims') is a correspondence in Arabic between an anonymous Christian monk from France and the Muslim scholar Abū l-Walīd al-Bājī of Spain. The monk's letter is addressed to al-Muqtadir, the king of Zaragoza ((r. 1049 – 1081)), inviting him to convert to Christianity. The king commissioned al-Bājī to write a response rejecting the overture. One letter from each correspondent survives in a single 14th-century manuscript, although there was apparently also an earlier exchange of letters.
