Wudhu

Finding blood on one's clothing after making ghusal

Q: Whilst doing compulsory ghusl, you get a cut from a razor when removing hair from private parts and you realise this after few hours only due to seeing some tiny spots of blood on underwear, then is the ghusl and all the namaz prayed valid? Should one repeat the ghusl and namaz? I'm not sure if this was flowing. The tiny spots of blood would equal to a small amount of blood less than a coin however, the spots were scattered over an area of the underwear and this area could potentially exceed the coin size.

Mazi

Q: I experience wet drops once I get to my partner without having any physical relation. Can I go for salaah or other things without "ghusal"?

Anal fistula

Q: I have a question that if one has an anal fistula (medical condition in which there is a connection between the lower part of the intestine and the skin) and there is a discharge from it which may be mucus, serous, pus or stool at times. It may be small in quantity and one may not even notice it.

1. Would the discharge break the wudhu and nullify the prayer

2. Sometimes I may not even know about the discharge, does one have to check before and after praying each time?

3. Sometime I need to do imamat, in that situation after salat should I ask the congregation to wait and check the discharge? It seems to prevent me from offering salat in congregation and constant fear of losing wudhu.
