Q: In my pregnancy I've been getting clear or yellow discharge very rugularly.

So sometimes if I'm out and I have slightly more than a Dirham size then I just sprinkle water over it and try to scrape it a bit but it's always wet, not dry. So sometimes I can't wash and change my underwear when I'm out.

Does sprinkling water over suffice?

It worries me because of my wudhu and salaah and it's validity.

Q: If I have olive oil in my hair and I make wudhu/ghusl afterwards, is my wudhu/ghusl accepted?

Q: Recently, I had two blisters on my arm, very close to each other, which ooze with pus. When I wash them, the pus starts coming out again. So I put plasters over both these blisters after the pus stopped flowing out. When it comes to performing wudhu, then how do I wash the narrow skin area between the two plasters without getting the plasters too wet?

Q:

1. Is it necessary to make wudhu for each salaah if one has discharge randomly throughout the day?

Q: If I use a miswaak before performing salaah at home alone, will I still get the reward of 70 times more as if I were to perform the salaah in the musjid?
