Ruling 260. Immersive wuḍūʾ means that one immerses his face and arms in water with the intention of performing wuḍūʾ. And what is apparent (ẓāhir) (42) is that there is no problem in wiping the head and feet with the wetness of the hands that were washed by immersion, although this goes against precaution. (43)
Ruling 261. In immersive wuḍūʾ, one must also wash his face and arms from top to bottom. Therefore, if at the time of immersing his face and arms in the water one makes the intention of wuḍūʾ, he must immerse his face forehead-first, and his arms elbow-first.
Ruling 262. There is no problem if one performs immersive wuḍūʾ for some parts [i.e. face/arms] and non-immersive for others.
