Benefits and Issues:
The meaning of fisq is "to go out," and due to being harmful and injurious, such creatures are outside the nature and temperament of other living beings.
Therefore, the Prophet (sallallahu alayhi wa sallam) referred to those creatures that are permitted to be killed within the Haram as "fasiq."
