‘Aishah said: “One of the wives of the Messenger of Allah observed I’tikaf with him, and she used to see red and yellow discharge, and sometime she would put a basin beneath her.”
حَدَّثَنَا الْحَسَنُ بْنُ مُحَمَّدِ بْنِ الصَّبَّاحِ، حَدَّثَنَا عَفَّانُ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ عِكْرِمَةَ، قَالَ قَالَتْ عَائِشَةُ اعْتَكَفَتْ مَعَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ امْرَأَةٌ مِنْ نِسَائِهِ فَكَانَتْ تَرَى الْحُمْرَةَ وَالصُّفْرَةَ فَرُبَّمَا وَضَعَتْ تَحْتَهَا الطَّسْتَ .
