Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 4|Chapter 15
وَ فِي خَبَرٍ آخَرَ: "أَنَّهُ إِنْ بَلَغَ بِهِ اَلْجُنُونُ مَبْلَغاً لاَ يَعْرِفُ أَوْقَاتَ اَلصَّلاَةِ فُرِّقَ بَيْنَهُمَا فَإِنْ عَرَفَ أَوْقَاتَ اَلصَّلاَةِ فَلْتَصْبِرِ اَلْمَرْأَةُ مَعَهُ فَقَدْ بُلِيَتْ ".
And in another narration: "If his insanity reaches the point where he no longer recognizes the times of prayer, they are to be separated. However, if he still recognizes the times of prayer, the woman should remain patient with him, for she has been tested."
