Is the wife sinful if she leaves her husband to neglect his prayers and delay performing them, and does not wake him for them to avoid problems?

The husband's negligence in prayer is a serious matter and a grave sin that necessitates repentance. Some jurists are of the opinion that intentionally abandoning even one prayer constitutes disbelief. The wife must continue to advise and guide him with gentleness and wisdom. If he persists in his negligence and unresponsiveness, then there is no good for her in remaining with him.
