Al-Kahf 19: And thus, We woke them up so that they would ask each other. One of them asked; “How long did you stay?” (They answered); “A day, or a part of a day.” they said. “Your Lord knows better how long you have stayed. Now, send one of you with silver (money) and see which food is cleaner, and bring provisions for you from it. And that person should act gently and not make anyone suspicious about you.”

Surah Al-Kahf, verse 19 Thus We, so that they might ask one another among themselves, woke them. However many years they lay, three hundred and some years, we do not know the exact count. Thus We woke them so that they might ask one another among themselves. One of them said: How long have you stayed? Some: We stayed a day or part of a day, they said. And some said: Our Lord knows best how long you stayed. Now send one of you with this silver coin of yours to the city, and let him see which of the city's food is cleaner, and if it is clean, let him bring you provisions from it. And let him be courteous. Let him act secretly.

And let him by no means make anyone aware of you. It says. Allah Almighty, so that they ask one another how long we slept, how long they remained asleep, and also to show people a miracle, wakes these valiant ones. These people who wake up ask one another. How long did we remain asleep, they say. Some of them say: like a day or part of a day. People who slept for several centuries, when they wake up, say to one another, like a day or part of a day, thinking they slept this long. Allah, who creates time within time, is capable of everything with His knowledge. In fact, it is in the world of the hereafter.

When we sprout from the earth like grass, when we are created anew, we will ask one another how long we lay under the ground. Some of us three days, some one day, and some of us, we lay something like a day, they will say. The honored angels on duty, who keep count of how long you lay under the ground, are the ones Allah Almighty asks. Again one of them said: The time we remained asleep, our Lord knows best. Thereupon they sent one of them, with the silver coin they had, to the city. With it they want to buy provisions. They agree among themselves as follows. One of their friends who will go to the city will buy the city's cleanest provisions, and he himself will act secretly, will not reveal their place to anyone, and will not do anything that arouses suspicion.

They did not know that King Dekyanos, who was searching for them, had died, that centuries had passed in between, and that the city had changed completely.
