That is a beautiful question, Semiannualchick!
We muslims believe that if people have done enough good deeds while on earth, and have practiced the six pillars when they experience death, they will be accepted by Allah to enjoy life with Him.
According to the Muslims believe, those who want to go to heaven, they need to follow the things that the prophet Muhammad did through the book of Hadiths.
On the Day of Judgment, all the dead people will be raised up and will sit before the throne of Allah to be judged no one can deny the Day of Judgment . When the Judgment Day comes, the book of deeds will be opened where everyone’s good and bad deeds were recorded and will be judged according to what they have done on earth. The righteous people will go to paradise and the wicked will be thrown into hell. They will have no more chance to repent so as to escape from hell but rather eternity they will for be in hell.
We believe that everyone’s bad and good deeds will be weighed or balanced by Allah. If the good deeds are more than the bad deeds, they will be automatically going to heaven. And if the bad deeds are more than the good deeds, they will go to hell. Those who are in heaven will have a chance to marry as many wives as he pleases, where as those who are in hell will have no chance to do so.
