31 – Muhammad ibn al-Husayn narrated to me, saying: Miskīn ibn ʿUbayd the Sufi narrated to me, saying: al-Mutawakkil ibn Husayn the devotee narrated to me, saying: Ibrahim ibn Adham said, “Sorrow is of two kinds: a sorrow that is for you and a sorrow that is against you. The sorrow that is for you is the grief you feel over the Hereafter and the good it contains; the sorrow that is against you is the grief you feel over this world and its adornment.”
