My wife does not perform Salah (Prayer). I advise her using all means, but she does not respond positively. Is it permissible to divorce her?
A: If you advise her and she does not respond, you are obliged to divorce her. According to Ijma` (consensus of scholars), she is a Kafir (disbeliever) when denying the obligation of Salah, and she is so whilst not denying its obligation according to the preponderant view. Allah (Exalted be He) says:
Likewise hold not the disbelieving women as wives
May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions.
