It is reported that Abū Qilābah – Allāh Have mercy on
him – said:
"It is only
the storyteller-preachers (al-qusās) who have
killed knowledge. A man listens to a storyteller for a year without really
learning anything that will last, whereas a man who sits with a scholar for an
hour learns what will last and benefit him before he even gets up."
Abō Nu’aym, Hilyatu Al-Awliyā` 2:287.
