Tahaarat

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. I feel ONE was maybe a scab, but I don't know  if both was for sure, must I do anything?

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?

Q: After having intercourse can a wife pray without taking a bath just doing wudu? If a bath is necessary, is washing the hair also necessary?

Q: A shafi follower makes wudhu according to Shafi'ee fiqh and then mistakenly touches his wife without any piece of cloth in between, and this person knows that according to the Hanafi maslak his wudhu did not break and goes and prays fardh salah according to Shafi'ee fiqh without renewing the ablution (to make his life easy). Will his Salaah be valid as he is basically a Shafi'ee. Note that he does not do this all times it occurs very rarely?

Q: I read in a Hadith that the wudhu performed after another wudhu earns one immense reward. Is it permissible after one wudhu to make another
wudhu based on this Hadith?

Q: I want to ask about the tree types of male liquids that may or may not break the ghusul, their types and form and what are the conditions that make ghusul wajib?

Q: I have a problem with my bladder (over-active bladder) where I find  it difficult to control it so at times I have wet myself and it has gone on the
carpet (a few drops) and with impure hands I have accidentally touched a door handle or wall. Now if I touch the same part with pure hands will my hands become impure or stand on the carpet with wet feet will it make my feet impure? Also I have a problem with a fluid that sometimes comes out of my private part. I always wash it but sometimes I don't realise it has come out until I dry myself after a shower but I have with the same hands touched the carpet or door handle or wall and put the towel on the floor, now if I touch the same part again will it make my hand or feet impure?

Q: Is wearing cosmetic coloured lenses haram? Can I wear coloured lenses occasionally? Also will wudhu be valid wearing lenses?

Q: If a person is partially bedridden and is unable to make wudhu without the assistance of another, can that person make tayammum and make salah and must that salah be repeated when that person recovers or finds someone to assist him to make wudhu?

Q: After shaving my private area there are very small cuts like little pricks. When I dab them with a tissue sometimes a little dot of blood appears and sometimes not. After making ghusl I apply oil to my body including private area I cannot be certain if it is bleeding after ghusl or not and if I have smeared the blood or not. Does it matter if it is smeared or not,the cut is like a prick of a pin and only a small dot of blood appears sometimes when I dab it.
