hello there , In Islam, heaven is divided by seven. Every part has its inhabitants -angels mostly- and also its guardians, and guess what a portal. Up there above heaven there is the throne, not a seat (nor a chair. It is a small child's Quartet where feet are usually set on ) but rather a piece of rock carried by eight the most big angels after that there is the paradise above it is a Sidr Tree of the end =because nobody has ever exceed close the wall . above it-throne- is wall of light where Allah established, there there is also the balance that will be weighting the deeds of creations, Preserved tablet or the divine tablet and more else .... the first food that the inhabitants of paradise will eat is the cod liver ,the time that will take to any one to travel to the above heaven only is higher than 50.000 years of what we count ...
