There is no doubt that the joy of the believers will be incomparable when they are led, group by honorable group, to the blessed Gardens of Paradise.

When they reach Paradise its gates will be opened for them, and they will be welcomed by noble angels  congratulating them on their safe arrival after suffering so much hardship and witnessing so much horror:

And those who feared their Rabb will be led to the garden in crowds, until, behold, they arrive there; its gates will be opened and its keepers will say “Peace be upon you! Well, have you done! Enter here, to dwell therein“. (39:73)

In other words, your words, thoughts, and deeds were good so your hearts and souls became pure and for that you deserve Paradise.
