Paradise has gates through which the believers, like the angels, will enter:
“‘Adn [Eden – everlasting gardens] of Paradise, whose doors will open for them” [38:50]
“…And angels shall enter unto them from every gate [with the salutation]: “Peace be unto you for that you persevered in patience! How excellent is the final home!” [13:23-24]
Allah (swt) has told us that these gates will be opened when the believers reach them, and they will be welcomed by the angels with greetings of peace:
“…til, when they reach it, its gates will be opened, and its keepers will say, “Salaamun ‘alaykum! You have done well, so enter here to abide therein.” [39:73]
The number of gates in Paradise is eight, one of which is called ar-Rayyaan, which is exclusively for those who fast.
al-Bukhaari and Muslim report from Sahl ibn Sa’eedi that the Messenger of Allah (saw) said,
“In Paradise there are eight gates, one of which is called ar-Rayyaan. No one will enter it except those who fast, and when they have entered it will be locked behind them and no one else will enter it”. [Ibn Katheer, an-Nihaayah, 2/214]
