Tahaarat

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?

Q: While making ghusl, I forgot to wash the inner part of my navel with my finger. Is the ghusl valid or do I have to repeat the ghusl? Is rubbing inside the navel necessary in ghusl?

Q: When I test my blood sugar, after the prick, the blood does not come out on it's own. I have to squeeze my finger to make the blood come out. Does my wudhu break through this?

Q: How many litres of water would Nabi (sallallahu alaihi wasallam) use for wudhu and for ghusl?

Q: Is colostrum najis. The fluid from the breast’s of a pregnant woman?

Q: If I flush the toilet after passing urine. While washing the areas of my body I have noticed the bidet splashing water inside the toilet and then onto the seat or floor. This water is coming from inside the toilet. The splashes are few. Some splashes I can wash off. But some fall on the ground.

Does this mean I have to thoroughly clean the floor after every use? 

Q: If one has oil in their hair and performs wudhu, is the wudhu valid?

Q: Because of my excessive masturbation, I got pre-ejaculation. If I see a girl continuously for some seconds mani comes gushing with desire automatically without even touching my private part and without me wanting mani to ejaculate. Is this because of my sickness? Most probably this is a sickness because when I defecate with force, then without desire mani comes out.

My question is:

Many times I see a girl and feel desire in my penis and I feel something is going to come out gushingly so what I do is, without holding or touching my penis I pinch myself on my legs or I think about something else so that the desire goes away and then after sometime mani comes out without any desire and also this comes without wanting to do it. Must I do ghusl for this?

Q: I would like to know my state of cleanliness because I am unsure. Due to my current illness, I have to wear specific sanitary items/nappies for urine leaks. I bought a new type of sanitary nappy and saw that the edges sat tightly around my body. However, at night when I turned, it moved a tiny amount. These nappies have inside cuffs that sit on the groin area for urine to stay inside, and then you have a tight elastic on the edge.

My question is, if the edge moved slightly, does this mean my clothes or hands are affected by the impurity if they get in contact with that area?  

Q: I'm a mazoor. I wanted to find out if I read Fajr Salaah, can I read Ishraaq Salaah with the same wudhu?
