1) Sometimes my skin near my nails peel and a small part of it still remains when I cut it off. Is that supposed to be considered an obstacle in the way of wudu or a part of skin. If this is an obstacle is doing tayamum in its place valid? 2) I read in the ayatollah’s website that if peeled skin is such that sometimes it sticks to body and other times hangs loose, that we must cut it off. What if after cutting the skin off a small portion of it remains and it’s not possible to cut it, or extremely difficult which cause pain, what should one do in this situation?
