"O youth! Make the Hereafter (Aakhirah) mandatory upon yourselves. We have seen many who desired the Hereafter, and they were granted the world (Dunya) along with it; but we have never seen even a single person who desired the world, and was granted the Hereafter along with it."
— Hasan al-Basri (Rahimahullah)
[Al-Wasaya al-Salaf lish-Shabab - Narrated by Al-Bayhaqi in Az-Zuhd (12)]
