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?
Answer:
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.
