Cleaning oneself with broken bone in cases of dire necessity

The questioner:
He says: Honorable Shaykh, may Allah grant you success, if a bone has been used for a long time and some of it has crumbled, is it permissible to use it for cleaning oneself?

The Shaykh:
No, absolutely not. It is not permissible to use it for cleaning oneself, no matter what is available, due to the generality of the prohibition by the Messenger (peace and blessings be upon him), and the cause remains. Yes.

The questioner:
And this one says: If I have nothing available except bone.

The Shaykh:
Even if the cause that it is food for the jinn is absent, the cause that it does not purify remains, as the Messenger (peace and blessings be upon him) said. Yes.

The questioner:
He says: If I have nothing available except bone, is it permissible to use it for cleaning oneself out of dire necessity?

The Shaykh:
No, my brother, it is not permissible. It is not permissible to use it for cleaning oneself. Take a handkerchief, or a rag, or something with you. Wipe the area and dry it. Yes. What do you mean, if Allah wills, that there are no handkerchiefs, rags, or things? Yes.
