If there is swelling on one’s face, arms, front of head, or feet as a result of being burnt or due to some other reason, it is sufficient to wash and wipe over it; and in the event that the swelling is pierced, it is not necessary to make water go underneath the skin.
If part of the skin has peeled, it is not necessary to make water go underneath the unpeeled part; however, in the event that the peeled skin is such that it sometimes sticks to the body and at other times it hangs loose, one must cut it off or make water go underneath it.
Ruling 292.* If a person doubts whether or not something is stuck to a part of the body on which wuḍūʾ is performed, in the event that his deeming this probable would be considered by people to be reasonable – for example, after plastering or painting one doubts whether or not plaster or paint is stuck to his hands – he must examine that part or rub his hands to the extent that it would normally give one confidence that it has been removed or water has gone underneath it.
