Is one who intentionally abandons prayer considered a disbeliever, and what should the wife do if he asks her to his bed, and for how long should she abstain, and how should his repentance be, and does he only make up for what he missed, or should he perform ghusl and say the Shahadah?

A husband abandoning prayers is a serious matter and a great sin that necessitates repentance. Some jurists have even gone so far as to consider one who intentionally misses a single prayer until its time expires to be a disbeliever. The wife must continue to advise him and remind him gently and wisely. We have previously clarified the ruling on a wife remaining with a husband who is negligent in prayer, the ruling on giving him his marital rights, advice for reforming a husband, and the ruling on repenting from abandoning prayer and whether it requires making up missed prayers.
