Faraaidh of wudhu

Masah of the head

Q: When making wudhu, how should the fingers be positioned during masah of the head? I have heard some ulama saying masah of head should be made with all 5 fingers with an open hand, or some say masah of head should be made with 3 fingers (middle ring and baby fingers). Please advise.

Finding a spec of paint on one's face after Salaah

Q: I performed asr once, broke my wudoo, went downstairs and the banisters of the stairs have paint bits that come off onto your hands [not wet paint, its like white specks that come off] and then I made wudoo' and went back upstairs using banisters, prayed and when I finished after a short while of being in my room I looked in the mirror and noticed a small speck on my eyelid and this speck doesn't really take much to take off, even a rub does it and now what do I do? Do I assume my prayer's valid as it could have been either times, but most likely the speck would have come off in wudoo as you wash your face three times?
