According to the Jamiatul Ulama KZN, it is permissible for women to apply nail polish.

Answer

Brother, the Natal Jamiat has joined the ranks of the juhala, modernists, deviates and fussaaq. The current chaps at the Jamiat's office are modernist youngsters lacking in proper Deeni knowledge. They have no munaasabat (compatibility) with Ilm -e-Deen, and they are completely bereft of Taqwa which is a vital

attribute for a Mufti. They have joined the ranks of the modernist NNB Jamiat of Fordsburg, the Qabar Pujaaris of Durban and the Zindeeq carrion halaalizers of the MJC who lack expertise in even the rudiments of Istinja.

These fellows who are experts in carrion halaalizing do not use water to purify themselves after discarding their loads of najaasat. Dump their corrupt 'fatwas' in the sewerage drain. Nail polish is haraam at all times. The Jamiat has been renamed, Jamiatul Juhala.
