How should a patient with a needle and supporting adhesive on the palm perform ablution, and is it enough to wipe water over the adhesive?

Summary

If the adhesive and needle can be removed without harm, they must be removed and ablution performed normally. If removal causes pain and worsens the condition, water may be wiped over the adhesive as with a wound dressing (jabirah), together with tayammum for the part not washed. In the Shafie school, the dressing must be applied while in a state of purity, and prayers must be made up if it was applied without purity, if it covers healthy skin excessively, or if it is on a tayammum limb. For long and difficult treatment, the fatwa allows following another school by only wiping water over the dressing, without tayammum and without making up prayers.
