Hadith 16884897 - وَ سَأَلَهُ عَمَّارٌ اَلسَّابَاطِيُّ : عَنْ رَجُلٍ أُخِّذَ عَنِ اِمْرَأَتِهِ فَلاَ يَقْدِرُ عَلَى إِتْيَانِهَا قَالَ "إِنْ كَانَ لاَ يَقْدِرُ عَلَى إِتْيَانِ غَيْرِهَا مِنَ اَلنِّسَاءِ فَلاَ يُمْسِكُهَا إِلاَّ أَنْ تَرْضَى بِذَلِكَ وَ إِنْ كَانَ يَقْدِرُ عَلَى إِتْيَانِ غَيْرِهَا فَلاَ بَأْسَ بِإِمْسَاكِهَا".
Hadith.4897 - Ammar Al-Sabati asked Imam Abu Abdullah (as) about a man who becomes unable to have intercourse with his wife.
Imam (as) replied: "If he is also unable to have intercourse with any other woman, then he should not keep her unless she is content with that. However, if he is able to have intercourse with other women, then there is no harm in him keeping her as his wife."
