Introduction
Nail polish is a chemical substance that is applied to the nails and, after drying, forms a solid, visible layer. When this layer forms on the nails, a question naturally arises about whether water reaches the nails during wudū’ or ghusl or not. If water does not reach the nails, then wudū’ and ghusl would not be considered valid according to prevailing Islamic law.
Looking at both Sunni and Shia schools, three broad positions emerge within the Ahl al-Sunnah: a strict prohibitive stance, a moderately strict position (associated with Imam Tirmidhi’s approach), and a position of permissibility. The Shia maraji’ (sources of emulation) have also issued rulings, largely requiring the removal of impermeable nail polish before wudū’ .
However, no specific text from the Quran or Sunnah addresses nail polish directly, nor does any fatwa or ijma’ (consensus) from the classical jurists exist on the matter—since nail polish did not exist in their era. This is a modern invention requiring contemporary Ijtihād guided by existing principles.
The first thing to state is that nail polish in and of itself is permissible, on account of it being classified as an item of adornment and beautification (zeenah). Islam does not prohibit adornment in principle; indeed, the Quran states:
"O Children of Adam! Take your adornment at every place of worship" (Al-A’raf: 31)
and
"Say: Who has forbidden the adornment of Allah which He has produced for His servants?" (Al-A’raf: 32).
Secondly, in the absence of any explicit prohibition, the Quranic principle of ease in religion is also best considered here:
"He has not placed upon you in religion any hardship" (Al-Hajj: 78)
"He has not placed upon you in religion any hardship" (Al-Hajj: 78)
and
"Allah intends ease for you and does not intend hardship" (Al-Baqarah: 185)
"Allah intends ease for you and does not intend hardship" (Al-Baqarah: 185)
Islamic jurisprudence holds that Allah does not burden people with what is beyond their capacity.
Conclusion
Having reviewed the Quranic verses, Prophetic traditions, the positions of the Hanafi, Shia, and other schools, and the principles of Islamic jurisprudence, the DIA concludes as follows:
1. Nail polish is a form of adornment (zeenah), which is permissible in Islam. Comparing it to cosmetics and attempting to measure it against the skin surface carries no juristic weight.
2. Requiring the removal of nail polish before wudū’ constitutes an unnecessary formality that is contrary to the Quranic and Sunnah principle of ease in religion, and contrary to the established practice regarding analogous substances such as henna and kohl.
3. In light of the guidance of the Prophet (pbuh) regarding women, the rulings of the jurists and mujtahidīn on various colouring agents and coatings, and the interpretive views rooted in the Sunnah, wudū’ is completely valid in the presence of nail polish, and prayer performed with such wudū’ is permissible.
4. The same applies to ghusl (obligatory ritual bath). In the presence of nail polish, both ghusl and wudū’ are valid without any doubt, and there is no prohibition in this matter.
