How does one perform the full ritual bath if he has a wound on his head and it is bandaged?

Question:
He says: Honorable Shaykh, may Allah grant you success, a man was injured in the head and has a bandage on it. How does he proceed during his full ritual bath from major ritual impurity? Is dry ablution with clean earth obligatory for him or not?

Answer:
The one who has a wound on his head or elsewhere, and has a dressing, a plaster, or a splint on it, wipes over the splint, the dressing, or the plaster, and this suffices in place of washing what is underneath. However, this is on the condition that the dressing, plaster, or splint is the size of the wound and does not contain anything extra; he removes the extra that is not needed.
