Wiping over adhesive dressings (Band-Aids) when doing wudu

I have something like abscesses on my feet, and the treatment requires that I put an adhesive dressing over them, so that I do not get any water on them when doing wudu. What is the ruling in this case?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

Your wudu is valid whether you wipe over the dressing or let water pass over it.
