Re: I just heard this…
Some of the salaf said that the Fire would come to an end after thousands of years and many ages have passed, and that they would die or be brought forth from it. But this view does not count for anything according to the majority of Ahl al-Sunnah wa’l-Jamaa’ah, rather it is false and is refuted by a great deal of evidence from the Qur’aan and Sunnah, as stated above. The view of Ahl al-Sunnah wa’l-Jamaa’ah is that Hell will abide for eternity and that its people will never come forth from it, and that it will never be destroyed, rather it will remain forever, according to the apparent meaning of the Qur’aan and of the Sunnah as proven from the Prophet (peace and blessings of Allaah be upon him). The evidence for that, apart from what has been mentioned above, is that Allaah says concerning the Fire (interpretation of the meaning):
“whenever it abates, We shall increase for them the fierceness of the Fire”
[al-Isra’ 17:97]
And Allaah says in Soorat al-Naba’, addressing the people of Hell (interpretation of the meaning):
“So taste you (the results of your evil actions). No increase shall We give you, except in torment”
[al-Naba’ 78:30]

In addition, those who rejected Islam will abide in Hell forever. I believe only the Muslim sinners if initially thrown into Hell would be taken out of it by the Will of Allah (SWT). Here’s more on it: Purification of the sinners .
Furthermore, Hell and Heaven already exist. Proof:
Allaah says concerning Hell (interpretation of the meaning):
“prepared for the disbelievers”[al-Baqarah 2:24]
The word prepared indicates that they exist at present.
In Saheeh Muslim (646) it is narrated from the hadeeth of Anas (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “By the One is Whose hand is my soul, if you had seen what I have seen, you would laugh little and weep much.” They said, “What have you seen, O Messenger of Allaah?” He said, “I have seen Paradise and Hell.”
