The young men in the story of Ashabul Kahfi were very lucky. They were able to experience a long deep sleep in the cave when time were bad. Then after more than three hundred years passed they woke up when time were good.
But people in Gaza are not as lucky as the young men in the story of Ashabul Kahfi. In the long time of chaos they didn't even have the chance to get enough sleep. They are forced to enjoy chaos endlessly until they sleep forever without waking up again because they have died.
