The People of the Cave rest for 309 years
The pious folk of the nation of Prophet ‘Isa (May peace be upon him) took refuge in a cave to save themselves and their faith. They remained in that cave for 309 years. Allah Most High says:
So they stayed in their Cave three hundred years, and (some) add nine (more). Surah Kahf (18:25)
These worshippers of Allah remained in the cave for 309 years. Their bodies didn’t age or change. For this whole period, they neither ate nor drank. This is a basic human need. No one can remain for more than a few days without eating or drinking, let alone 300+ years.
Through the great power of Allah Most High, the People of the Cave spent 309 years without eating or drinking. Their bodies remained safe and even the dog on their door remained safe.
