Is it permissible to wipe over the feet during ablution instead of washing them, due to the presence of fungi that are affected by water?

If it is possible to wash between the toes during ablution, it is obligatory. However, if washing would lead to illness, worsen an existing one, or delay recovery, it is permissible to wipe over the painful area between the toes. If washing the feet does not cause pain, then they should be washed; otherwise, it is permissible to wipe over the entire foot. And whoever fears harm from water on a wound should wipe over it and wash the rest of the limb.
