Perhaps Asín Palacios is best remembered for his 1919 book, "La Escatologia Musulmana en la Divina Comedia", which sparked lively and extended discussions among Dante scholars. Asíin here suggests Islamic sources for the theological landscapes used by the Italian poet Dante Alighieri (1265–1321) in his work "La Divina Commedia", written c.1308 to 1320. Specifically, Asín compares the Muslim religious literature surrounding the night journey wal-Mi'rag of Muhammad (from Mecca to Jerusalem and thence up with the prophets through the seven heavens), with Dante's story describing his spiritual journey in which he meets various inhabitants of the afterlife and records their fate.
