Wuzu Over Tattoo
Walikumsalam! As long as it remains clear that these are at root ijtihadi matters, where no explicit guidance is contained in Quran and Sunnah, therefore scholars make the informed decision considering the overall framework of religion. Regarding Wuzu over Nailpolish, Ghamidi Sahab considers it more close to the siuation where feet are covered with socks and we are allowed to do masah over them; Similarly, when Nailpolish is applied after doing Wuzu, the next wuzu over them will be considered Masah over nails.
