It is reported that Im�m Muhammad ibn. S�r�n - All�h have mercy on him - said:There were people who abandoned knowledge and sitting with the scholars, and [instead] took to their chambers and prayed until their skin dried [from exertion in worship]. Thereafter they began to contradict the Sunnah and thus were destroyed. By All�h, never does a person act without knowledge, except that he spoils and corrupts more than he fixes and rectifies....(Al-Asbah�n�, Al-Targh�b wa Al-Tarh�b 3:98)
