Q: I had a small cut on my finger. There was a little bit of water in the wound but it was not flowing, it was still within the wound. I wiped some cream on the wound and then creamed my body. At the time of wiping I was under the impression that the wound had heeled, but after the cream had dried I noticed there was still water within the wound. Did I spread any najis?

1. I suffer from droplet problem. After passing urine I wash and put toilet paper till all the droplets come out. However sometimes the toilet paper moves out of place. Does this make my underwear napaak and do I have to wash it?

Q: In ghusl, I felt behind my ear two things that are abnormal like scratch able dots it felt like. Anyway after ghusl and after wudoo I scratched one dot and the area was now a bit smooth, but I don't know what was there or would it affect my tahaharah.

Q:

1. I had a scratch on my knee which I thought was almost healed. However, at the end of the day, I noticed many small spots (which I assume was discharge from the wound) on my pants and kurta around the knee area. I do not know when this occurred, but it is likely that some of the discharge occurred while performing sajdah. Do I have to repeat all salaah/tilaawat for that day?
2. If one covers a wound with a bandage, and blood may or may not flow onto the bandage, would it be permissible to perform salaah in that condition, or does one have to be certain that the bleeding has stopped?
3. Referring to (2), can one lead the salaah in that condition?
