Hadith.3266 - In the narration of Ahmad ibn Abi Abdillah al-Barqi, Imam Ali ibn Abi Talib (as) said:
"It is obligatory upon the Imam to imprison the corrupt among the scholars, the ignorant among the physicians, and the bankrupt among those who rent out property."
And Imam (as) also said: "Imprisonment by the Imam after the implementation of the legal punishment is oppression."
