The Prophet ﷺ said:
In Paradise, there are rooms the outside is seen from the inside and the inside from the outside, Allah has prepared it for whoever:
-Feeds the people,
-Continuously fasts,
-Prays at night while the people are asleep.
Reported by At-Tabaraani.
“O feet of patience, keep going, for what remains is only a little. Remember the sweetness of worship, then the bitterness of striving will become easier for you.”
(al-Fawaa’id by Ibn Al-Qayyim)
Indeed, there have come to you proofs from your Lord.
So whoever chooses to see, it is for their own good.
But whoever chooses to be blind, it is to their own loss.
And I (Muhammed) am not a keeper over you.
[Quran 6:104]

Calamities = 1. Expiation of sin and 2. Raising of one's status:
“There is nothing that befalls a believer, not even a thorn that pricks him, but Allah will record one good deed for him and will remove one bad deed from him.” Narrated by Muslim.
There are 3 things which, once they happen, it will do a person no good to believe, if he believed not before, nor earned good through his faith:
1. Rising of the Sun from the West
2. Apperance of the Dajjaal
3. Apperance of the Beast
(Reported by Muslim, 2/195).
