Quran 18:18 – Ashab-e-kahf And Mention Of Their Turning Sides While Asleep
Thank you Dr Irfan for your reply. But if they could stay alive for 300 years without other necessities for e.g. food and water, why was turning sides so important?
Allah arranged that happening that way. They were hibernating. The rest of the things they needed like warmth of sun and turning sides were to keep their bodies sound.
