It is narrated from Imam Hussain (AS) who said:

Beware that the sweetness and bitterness of the world, is nothing but a dream, and the real awareness and vigilance is in the hereafter; and the saved and blessed one is the one who is successful in the hereafter; whilst the unfortunate person is the one who is ill-fated in the hereafter [1].
