THE EARS ARE ACTIVE DURING SLEEP
So We sealed their ears [with sleep]
in the cave for a number of years. (Qur'an, 18:11)
The original Arabic of the phrase "We sealed their ears" in the
Qur'an is the verb daraba. This bears the metaphorical meaning of
"We have made them sleep." Used in reference to the ears, daraba
means "preventing the ears from hearing." The fact that only the
sense of hearing is mentioned here is very significant.
According to recent scientific discoveries, the
ear is the only sensory organ active while a person is sleeping.
