Tahaarat

Q: If a root of a hair falls in ماء قليل (little water), does it become najis?

Q: If during gusul e janabat I have something in my tooth cavities that can't be got rid off easily, will it make my fard of washing the mouth incomplete? Is the filling of the mouth fully with water fard or washing the teeth as well? What if I have my teeth filled medically (ionic filling)?

Q: Most of the time after urinating a drop of urine comes out.  I was told if I am a ma'zoor my wudu wouldn't break if urine comes out and I can pray more than 1 salah with 1 wudu e.g pray zuhr, asr with 1 wudu so is it correct I can pray more than 1 salah with 1 wudu?

Q: Sometimes I notice a stain (white, mazi) on my pants but I don't know when it came out of my private part. I don't know if I need to repeat the previous salaat or not? What should I do in this situation?

Q: In wudhu if I touch my husband wudhu breaks? While performing umrah if I hold my husbands hand will my wudhu break? Please tell me.

Q: After intercourse with ones spouse, is it necessary to wash all the bedding and linen? Or just the spot that's messed? Also after one performs ghusl , semen comes out, is it necessary to repeat ghusl?

Q: If someone started bleeding at zuhr time and had not prayed zuhr until 10 to 15 mins before asr and then they prayed zuhr. Then at start of asr they are still bleeding so they make wudu and pray asr. Now if they stop bleeding at asr time, will they have to repeat their zuhr or not? I heard there is a difference of opinion.

Q:

1. Someone told me that if only a drop of urine comes out you still have your wudu because a drop is less than a penny (coin), is this true?
2. All impurity which is less than 3 to 5 centimetres in diameter is excused. I am sure two drops of urine on your clothes will not make a circle which is more than 3 centimetres, is that true?

Q: Please can  you tell me am I making ghusal right as I was thought this way in school.

1. Make niyyah
2. Wash private parts
3. Wash hands
4. Make complete wudu
5. Pour water over entire body 3 times.

I have been told this is incorrect. An is it the same for males?

Q: If there is no water in the house for gusul and we cannot ask it from neighbour also, can we do tayyamum for namaz? I reside in Mumbai city.
