The Ruling on Killing the Five Noxious Creatures and the Spider

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Is there a legal wisdom in the command to kill the noxious creatures? Are all types of crows considered among the noxious creatures and thus to be killed? And is there a text stating that the spider should not be killed or harmed? This is widespread among the common people.

Answer:
Killing the five noxious creatures is something the Prophet (peace and blessings be upon him) commanded in both the permitted areas and the Sacred Precinct. The term "noxious creatures" is derived from "fisq" (open sinfulness), which means going out, because they have gone out from the custom of created beings by causing harm; they cause harm. The wisdom in killing them is to repel their harm, the wisdom in killing them is to repel their harm from the individual and from the people; this is the wisdom. As for the spider, I have not heard anything about it; I do not know anything about it. Yes.
