Ruling 104 — Purification (Ṭahārah)

Based on obligatory precaution, the entire body of a disbeliever who is not kitābī [i.e. not from among the People of the Book] is impure; this includes his hair, nails, and the moisture from his body. As for an apostate (i.e. someone who is no longer a Muslim), the rule that applies to him is determined by his new religious status. Therefore, if the apostate person becomes a kitābī disbeliever, he is pure; and if he becomes a non-kitābī disbeliever, he is impure based on obligatory precaution.
