Ruling 242 — Purification (Ṭahārah)

The direction in which one must wash the arms is from top to bottom [i.e. in a direction towards the fingertips]. The same applies, based on obligatory precaution, to washing the face [i.e. it must be washed in a direction towards the chin]. If a person washes from bottom to top, the wuḍūʾ is invalid.
