Furthermore, it is established that “the Prophet, may Allah bless him and grant him peace, gave his hair to the Muslims when he shaved his head,” and that “he, may Allah bless him and grant him peace, would cleanse himself after relieving himself with water or stones.” Whoever equates hair with urine and feces has therefore made an obvious error.

As for bones and similar parts, if someone argues that they fall within the category of carrion because they have sensation and feel pain, the reply is:

“You yourselves have not applied the wording in its full generality. Creatures without flowing blood, such as flies, scorpions, and beetles, do not render anything impure according to you and the majority of scholars, even though they have died and lost their animal life.”

It is established in the Sahīh that the Prophet, may Allah bless him and grant him peace, said:

“If a fly falls into the vessel of any one of you, let him immerse it and then remove it, for one of its wings carries disease and the other carries a cure.”

Even those who regard such creatures as impure hold, according to one of their two views, that they do not render impure the liquids into which they fall, because of this hadith.

Since this is so, it becomes clear that the reason carrion is impure is precisely that blood is retained within it. A creature without flowing blood has no blood that flows, so when it dies, no blood is retained within it, and it therefore does not render anything impure. Bones and similar parts have even stronger grounds for not rendering anything impure than these creatures do: a bone contains no flowing blood, nor does it move voluntarily except as a subordinate part of the body.

If, then, a whole animal endowed with sensation and voluntary movement does not render anything impure because it contains no flowing blood, how could a bone containing no flowing blood render anything impure?
