applying nail polish to one's nails a lady should perform ablution. All
subsequent ablutions can then be performed with the nail, polish applied.
However, one thing a Muslim woman must always keep in mind: growing nails is
explicitly forbidden in Islam. Most women who use nail polish normally grow --
in fact "nurture" nails.
2) The real
reason behind masah on socks or similar footwear is raf`ay haraj ie to provide
ease. The reason is not to actually clean something. Therefore, it is okay to
do masah on the stockings even if they partly stop dust, dirt and water.
3) Women are
allowed to cut their hair in any decent style they want. The only haircut
forbidden is that which makes them resemble men. The reason for this is that
Allah has made men and women as two distinct entities upon which is built the
whole edifice of a society; each has distinct functions and distinct
responsibilities; copying each other in spheres specifically meant for the one
is against the fitrah (human nature) made by Allah and breeds wrong attitudes,
desires and inclinations.
hair, I believe, makes women resemble men and hence it is undesirable.
