Answered by Ustadha Hedaya Hartford, SunniPath Academy Teacher
Is it permissible to use a nail whitener pencil on the inside bit of the nail to make the tips of the nails look whiter?
In the name of Allah, Most Gracious, Most Merciful
It seems as if most pencil whiteners leave a barrier such that one”s ablution is not valid if made after using it.
Note that it is reprehensible to let the nails grow long (Al-Durr al-Mukhtar 5:260) even if it is done for one”s husband.
And Allah Most High knows best.
