الدارمي:٨٤٩أَخْبَرَنَا حَجَّاجُ بْنُ مِنْهَالٍ حَدَّثَنَا حَمَّادٌ عَنْ حُمَيْدٍ قَالَ قِيلَ لِبَكْرِ بْنِ عَبْدِ اللَّهِ إِنَّ الْحَجَّاجَ بْنَ يُوسُفَ يَقُولُ إِنَّ الْمُسْتَحَاضَةَ لَا يَغْشَاهَا زَوْجُهَا قَالَ

بَكْرُ بْنُ عَبْدِ اللَّهِ الْمُزَنِيُّ «الصَّلَاةُ أَعْظَمُ حُرْمَةً يَغْشَاهَا زَوْجُهَا»
