The prophet Sallallahu alaihi wasallam said: The fire of hell us veiled with passion and desire while Paradise is veiled with hardships. (Al-Bukhari)

The prophet (Sallallahu alaihi wasallam) said: Nothing increases one's lifespan except good deeds and nothing repels Divine decree du'a and verily, a person may be deprived of sustenance due to a sin that he does.
