The ruling on a woman using makeup and nail polish

Question:
May Allah reward you with good, and may He do you good. The listener Abdul-Latif Barish from Algeria sent a question, saying: Is it permissible for a woman to use makeup in its various forms, especially nail polish? As we know, the perfection of the validity of wudu' (ablution) requires passing water over the entire [body]. If the nails are covered, is the wudu' valid? May Allah reward you with good.

Answer:
What will the woman use? What is customary for adornment and beautification? On the condition that she does not go out to the street with it or show it to people, but rather it remains in her home with her husband and her mahram (relatives one may not marry), where there is no fitnah (trial, discord or temptation) or evil.
As for painting the nails with dyes that have no thickness and dry on the surface, there is no harm in that, such as henna and khatib (dye) and the like. However, painting them with something that dries on the surface and has a thick layer that prevents water from reaching the nail is not permissible, and it must be removed. If she applies it and performs wudu' while it is on her nail, preventing water from reaching the nail, then her wudu' is not valid, because it is an incomplete wudu'.
The Prophet (peace and blessings be upon him) saw a man who had a spot on his foot the size of a dirham that water had not reached, and he said: "Go back and perfect your wudu'." He also said: "Woe to the heels and long feet from the Fire." Therefore, perfecting the wudu' and completing it on all limbs is obligatory, and the prayer is not valid without it. Among these limbs are the nails, which must be free from anything that prevents water from reaching them, such as lacquer and the like. Yes.
