عَنْ رَجُلٍ طلَّقَ امْرَأَتَهُ وَهِيَ تَحِيضُ تَمْكُثُ ثَلَاثَةَ أَشْهُرٍ ثُمَّ تَحِيضُ حَيْضَةً ثُمَّ يَتَأَخَّرُ عَنْهَا الْحَيْضُ ثُمَّ تَمْكُثُ السَّبْعَةَ الْأَشْهُرَ وَالثَّمَانِيَةَ ثُمَّ تَحِيضُ أُخْرَى تَسْتَعْجِلُ إِليْهَا مَرَّةً وَتَسْتَأْخِرُ أُخْرى كَيْفَ تَعْتَدُّ؟ قَالَ «إِذا اخْتَلَفَتْ حَيْضَتُهَا عَنْ أَقْرَائِهَا فَعِدَّتُهَا سَنَةٌ»
