Alma 40

A few days ago, I mentioned that I believe heaven and hell as mentioned in the scriptures would also be synonymous as  paradise and prison (with outer darkness) as Alma teaches Corianton -

"Now, concerning the state of the soul between death and the resurrection—Behold, it has been made known unto me by an angel, that the spirits of all men, as soon as they are departed from this mortal body, yea, the spirits of all men, whether they be good or evil, are taken home to that God who gave them life.
12 And then shall it come to pass, that the spirits of those who are righteous are received into a state of happiness, which is called paradise, a state of rest, a state of peace, where they shall rest from all their troubles and from all care, and sorrow.
13 And then shall it come to pass, that the spirits of the wicked, yea, who are evil—for behold, they have no part nor portion of the Spirit of the Lord; for behold, they chose evil works rather than good; therefore the spirit of the devil did enter into them, and take possession of their house—and these shall be cast out into outer darkness; there shall be weeping, and wailing, and gnashing of teeth, and this because of their own iniquity, being led captive by the will of the devil."  (Book of Mormon | Alma 40:11 - 13)

Of such, Joseph Fielding Smith explained -

“These words of Alma as I understand them, do not intend to convey the thought that all spirits go back into the presence of God for an assignment to a place of peace or a place of punishment and before him receive their individual sentence. ‘Taken home to God,’ (Compare Ecclesiastes 12:7) simply means that their mortal existence has come to an end, and they have returned to the world of spirits, where they are assigned to a place according to their works with the just or with the unjust, there to await the resurrection.

‘Back to God’ is a phrase which finds an equivalent in many other well known conditions. For instance: a man spends a stated time in some foreign mission field. When he is released and returns to the United States, he may say, ‘It is that phrase in a qualified sense …. Solomon makes a similar statement: ‘Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.’ The same idea is frequently expressed by the Latter-day Saints” (Gospel Truths, p. 73.) (Joseph Fielding Smith, Answers to Gospel Questions, 5 vols. [Salt Lake City: Deseret Book Co., 1957–66], 2: 85

Alma also explains what many Christians consider to be the resurrection -

"...there are some that have understood that this state of happiness and this state of misery of the soul, before the resurrection, was a first resurrection.  Yea, I admit it may be termed a resurrection, the raising of the spirit or the soul and their consignation to happiness or misery, according to the words which have been spoken."  (Book of Mormon | Alma 40:15)

But that is truly not the case for -

"...it meaneth the reuniting of the soul with the body..."  (Book of Mormon | Alma 40:18)

Thus what many consider heaven and hell is a period before the resurrections and final judgement.
