What you should do in the following situations

Tahaarah (purity and cleanliness)

Dressings on wounds

If a person has an injury in any part of his body that should be washed during wudoo’, and cannot put a band-aid or dressing on it, then he should do wudoo’, and do tayammum for the wounded part (al-Mughni ma’a al-Sharh al-Kabeer, 1/282). He does not have to wash the wounded part if this will be harmful.
