Ruling 613 — Purification (Ṭahārah)

If a part of the corpse becomes separated – even if it is its hair, nail, or tooth – it must be buried with the body. In the event that the separated part is found after the body has been buried, then based on obligatory precaution, even if it is its hair, nail, or tooth, it must be buried in a different place. Furthermore, it is recommended to bury nails and teeth that were separated from a person’s body when he was alive.
