Musannaf Ibn Abi Shaybah 37953 — The words of al-Hasan al-Basri

It is narrated from Asim that he said: I never heard al-Hasan cite any verse of poetry as an illustration except this verse: "He is not the only dead one who has died and found rest; the dead one is he who is dead among the living." Then al-Hasan said: By Allah, he (the poet) spoke the truth. A person can be alive while his heart is dead.
