These are those who do not migrate, and have not a complete Faith, either. There are some people who are inside a polluted society but they try to protect themselves from pollution, (like the of the Cave). There are also a group of people who change others and improve their polluted society into a good one, (like prophets and saints).
However, there are some Islamic traditions which indicate that the of the Cave will be amongst the friends and helpers of Hadrat Mahdi (May Allah hasten his glad advent).
“And We strengthened their hearts, when they stood up and said: ‘Our Lord is the Lord of the heavens and the earth; never will we call upon any god besides Him, for then we should have uttered extravagantly’.” 15. “These our people have taken gods other than Him; why do they not bring any clear authority regarding them? Who is then more unjust than he who forges a lie against Allah?” 16.
“And when you withdraw from them and what they worship save Allah, then seek refuge in the Cave, (and) your Lord will shower on you of His mercy, and furnish you with a gentle issue of your affair.” Following the former discussion, the Qur’an implies that their hearts were given strength when they stood up and said that their Lord is the Lord of the heavens and of the earth, and that they would never call upon any god other than Him, since if they did so, they would indeed had uttered an extravagance.
The verse says: “And We strengthened their hearts, when they stood up and said: ‘Our Lord is the Lord of the heavens and the earth; never will we call upon any god besides Him, for then we should have uttered extravagantly’.” In fact, those faithful youths, in order to prove Unity and negate any gods attached a manifest proof and said that they saw clearly that the heavens and the earth had a Lord, and the existence of the regulation of creation was a reason for their existence, and they were a part of that existence.
