وَ رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ إِبْرَاهِيمَ اَلْكَرْخِيِّ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنْ رَجُلٍ لَهُ أَرْبَعُ نِسْوَةٍ فَهُوَ يَبِيتُ عِنْدَ ثَلاَثٍ مِنْهُنَّ فِي لَيَالِيهِنَّ وَ يَمَسُّهُنَّ فَإِذَا بَاتَ عِنْدَ اَلرَّابِعَةِ فِي لَيْلَتِهَا لَمْ يَمَسَّهَا فَهَلْ عَلَيْهِ فِي هَذَا إِثْمٌ قَالَ "إِنَّمَا عَلَيْهِ أَنْ يَبِيتَ عِنْدَهَا فِي لَيْلَتِهَا وَ يَظَلَّ عِنْدَهَا صَبِيحَتَهَا وَ لَيْسَ عَلَيْهِ أَنْ يُجَامِعَهَا إِذَا لَمْ يُرِدْ ذَلِكَ ".
Al-Hasan ibn Mahbub narrated from Ibrahim al-Karkhi, who said: I asked Abu Abdillah (a.s) about a man who has four wives and spends the night with three of them during their respective nights, and he has relations with them. However, when he spends the night with the fourth one on her night, he does not have relations with her. Is there any sin upon him in this matter? Imam (a.s) said: "It is only obligatory upon him to spend the night with her on her night and to remain with her until the morning. There is no obligation upon him to have relations with her if he does not wish to do so."
