Musannaf Ibn Abi Shaybah

It is narrated from Imran Qasir that he says: I asked Hasan about something, so I said, "Indeed, the jurists say such and such." Hasan replied: "Have you ever seen a faqir (ascetic) with your own eyes? A faqir is one who is disinterested in the world, is insightful in his religion, and is constant in the worship of his Lord."
