People of Kahf: Place and Period

Tafsir authority al-Qurtubi of al-Andulus (Spain) has reported some events at this juncture in his Tafsir. Some of these events, that belong to different cities, he had heard or seen himself. First of all, he says on the basis of a report from Dahhak that al-Raqim is the name of a town in Rum (the Greco-Roman territory) where twenty-one men are lying in a cave as if they are sleeping. Then, he reports from Tafsir authority, Ibn ` Atiyyah that he had heard from many people that there was a cave in Sham (Syria) which had some dead bodies in it. Attendants said that they were the ones called the People of Kahf. And adjacent to the cave, there was the structure of a mosque and residential house called Raqim. In addition to the dead bodies, the skeleton of a dead dog was also present there.
