What happens to us after we die?

This is all gross falsehood! If you go to hell it is forever. Those who say that muslims will only go to hell for a little bit of time and then get a one-way pass to heaven are attributing lies to GOD. They are wicked. The Quran says this. See below.[Quran 2:80-82] Some have said, “Hell will not touch us, except for a limited number of days.” Say, “Have you taken such a pledge from GOD - GOD never breaks His pledge - or, are you saying about GOD what you do not know?” Indeed, those who earn sins** and become surrounded by their evil work will be the dwellers of Hell;** **they abide in it *FOREVER.***As for those who believe, and lead a righteous life, they will be the dwellers of Paradise; they abide in it forever.

[Quran 4:14] As for the one who disobeys GOD and His messenger, and transgresses His laws, He will admit him into Hell, wherein he abides FOREVER. He has incurred a shameful retribution.
The word ‘Muslims’ means ‘one who submits to the will of GOD’. So, if a muslim is committing sin and transgressions than he is NOT submitting to the will of GOD. Hence, he is not a muslim, but a hypocrite. The Quran is very clear on this.
