It is narrated from Hawshab bin Aqil (may Allah have mercy on him) that a man narrated a hadith in the presence of al-Hasan (may Allah have mercy on him). Al-Hasan (may Allah have mercy on him) asked: "Who told you this?" He said: "The jurists (fuqaha)." He (may Allah have mercy on him) said: "Have you ever actually seen a jurist with your own eyes?" Then he said: "Do you know who the jurist is? The jurist is the one who is detached from this world, eager for the Hereafter, has deep insight into this religion of his, and holds firmly to knowledge."
