Can I wear nail polish while during the Salat? Is it forbidden to use that product even if mine is not coloured?
Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
There is no harm in using nail polish since the customs are basically permissible as long as they are not for cheating or misleading, such as to deceive the one who proposes to a girl. She uses nail polish to make him believe that her hands are pretty while they are not so.
It is also not permissible if she intends by that practice to imitate Kafir or dissolute women. For example, she uses a peculiar colour or style similar to a known Kafir or dissolute woman. In this case, it is forbidden for the reason of imitation even though it is permissible otherwise.
If the ingredients of the nail polish are forbidden such as lard or the like, then using it is forbidden.
Moreover, whoever uses it has to remove it before making ablution or taking a bath if it prevents water from reaching the body parts.
Allah knows best.
