Dry blood on the head due to psoriasis
Q:
1) If a person has severe psoriasis of the scalp that bleeds and dries up, then he makes wudhu as normal, but some dry blood remains on his scalp, would the wudhu be valid?
2) If this person touches the blood as his head is bleeding then wipes it on his kurtha by mistake, makes wudhu and performs salaah in that condition where there is some blood on his kurtha, is the salah valid?
