The question is whether this incident is recorded in any other place excepting the Qura’n and is there any reference to it in the Torah and Bible?

The answer to the first question is “yes” and the second is “no”

According to the historians this incident occurred a long time after the birth of the messiah. Some have given it a time frame of 249 to 251 A.D. and this is why there is a chance that this is not mentioned in both the old and the new testaments.

The book Alami Qura’n says that the Europeans have written a brief account of the companions of Kahf as follows:

Between 249 and 251 A.D. Dakhianus oppressed the Christians so seven young men from respectable families who were well placed took shelter in the Cave. Dakhianus sealed the cave’s mouth with a wall so that they would die inside with hunger and thirst but they went into a deep sleep. They woke up after 157 years in the rule of Thaddeus II. The Europeans call them “The seven sleepers of Ufsoos.”

Another portion of the same book says:

“The story of the sleepers of the cave was first written and published by7 Zach of Sarwick in cyriac magazine in the 5th century A.D. Zach was the head priest of the church of Syria. A person named Gogoeus translated the incident from cyriac to Latin. (1)

We find this incident repeatedly told in Islamic as well as western and eastern literature and there are hints about in Russian and African literature also. (2)

This incident is not just recorded in the Qura’n only but other historical signs also point to it.
