Muhammad ibn Ya'qub narrated from Muhammad ibn Yahya, from Muhammad ibn al-Husayn, from Safwan ibn Yahya, from Abd al-Rahman ibn al-Hajjaj, who said: I asked Abu al-Hasan عليه السلام about a person with a fracture who has splints on it or someone with wounds - how should he perform wudu (ablution), ghusl janabah (ritual purification after major impurity), and ghusl jumu'ah (Friday bath)? Imam عليه السلام said: "He washes what he can reach with water from the areas that are exposed and not covered by splints. He leaves the parts that he cannot wash and does not remove the splints or tamper with the wounds."
