Miguel Asín Palacios was a Spanish scholar of Islamic studies and the Arabic language, and a Roman Catholic priest. He is primarily known for suggesting Muslim sources for ideas and motifs present in Dante's Divine Comedy, which he discusses in his book La Escatología musulmana en la Divina Comedia (1919). He wrote on medieval Islam, extensively on al-Ghazali. A major book El Islam cristianizado (1931) presents a study of Sufism through the works of Muhyiddin ibn 'Arabi of Murcia in Andalusia. Asín also published other comparative articles regarding certain Islamic influences on Christianity and on mysticism in Spain.

The Divine Comedy is an Italian narrative poem by Dante Alighieri, begun c. 1308 and completed around 1321, shortly before the author's death. It is widely considered the pre-eminent work in Italian literature and one of the greatest works of Western literature. The poem's imaginative vision of the afterlife is representative of the medieval worldview as it existed in the Western Church by the 14th century. It helped establish the Tuscan language, in which it is written, as the standardized Italian language. It is divided into three parts: Inferno, Purgatorio, and Paradiso.
