Is it permissible to use a nail polish if the ingredients are halaal?

Answer

Firstly, there is no such nail polish available. Secondly, nail polish forms an impervious layer on the nails regardless of claims to the contrary. Based on these two factors, using nail polish is haraam. Neither will wudhu nor Salaat be valid.

Assuming that all the ingredients are halaal, then too it is haraam to use nail polish because it renders wudhu invalid. Removing the nail polish every time wudhu has to be made is impractical. In fact, the nail polish will rather lead to abandonment of Salaat. Generally, women who roam in the public utilize this satanic substance for haraam purposes - to attract the gazes of the fussaaq and fujjaar.
