[18:16]

And when ye withdraw from them and that which they worship except Allah, then seek refuge in the Cave; your Lord will spread for you of His mercy and will prepare for you a pillow in your plight.

[18:17]

And thou mightest have seen the sun when it rose move away from their cave to the right, and when it set go past them on the left, and they were in the cleft thereof. That was (one) of the portents of Allah. He whom Allah guideth, he indeed is led aright, and he whom He sendeth astray, for him thou wilt not find a guiding friend.

[18:18]

And thou wouldst have deemed them waking though they were asleep, and We caused them to turn over to the right and the left, and their dog stretching out his paws on the threshold. If thou hadst observed them closely thou hadst assuredly turned away from them in flight, and hadst been filled with awe of them.

[18:19]

And in like manner We awakened them that they might question one another. A speaker from among them said: How long have ye tarried ? They said: We have tarried a day or some part of a day, (Others) said: Your Lord best knoweth what ye have tarried. Now send one of you with this your silver coin unto the city, and let him see what food is purest there and bring you a supply thereof. Let him be courteous and let no man know of you.

[18:20]

For they, if they should come to know of you, will stone you or turn you back to their religion; then ye will never prosper.
