The eminent Muslim scholar and renowned Da`iyah, Sheikh `Abdel Khaliq Hasan Ash-Shareef, states: “Not wearing the hijab is not one of the acts that nullify ablution. So, a lady can pray after concluding wudu without redoing wudu’.
However, women should know that the Lord Who orders her to perform ablution and to offer Prayer is the same One Who commands her to wear hijab and that the real righteous Muslim is he or she who does not select from his/her religion what fits his/her desires. Rather, he/she has to subjugate his/her own desires for the religion of Allah.”
