أَخْبَرَنَا يَحْيَى بْنُ بِسْطَامَ ، حَدَّثَنَا لَيْثُ بْنُ سَعْدٍ ، عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ ، عَنْ أَبِي الْخَيْرِ ، عَنْ عُقْبَةَ بْنِ عَامِرٍ ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ :" لَا تَدْخُلُوا عَلَى النِّسَاءِ ".
قِيلَ : يَا رَسُولَ اللَّهِ إِلَّا الْحَمْوُ.
قَالَ : " الْحَمْوُ : الْمَوْتُ ".
قَالَ يَحْيَى : الْحَمْوُ : يَعْنِي قَرَابَةَ الزَّوْجِ
