Scars
Q: A person has a rash like eczema on his scalp. Sometimes it bleeds a little. At night unconsciously he scratches it and it bleeds sometimes. Now it is very difficult to know where it bled etc, and at fajr time he simply makes wudhu as normal without washing his head. There may be some dry blood on his head. Is performing salaah in this manner permissible or does he have to wash his head completely every morning to make sure there is no blood? Sometimes for Fajr he has to be the imam of a small musallah when the Imam is not there?
