(Imām Bukhārī narrates): Qutaibah narrated to us, he said: Yazid bin Zurai' narrated to us, from Khalid, from Ikrimah, from Hazrat Aisha (may Allāh be pleased with her), she says that
one of the Prophet's ﷺ wives sat in i'tikaf with him; she would see blood and a yellow color, and there was a tray beneath her, and she used to pray.
حَدَّثَنَا قُتَيْبَةُ، قَالَ: حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ خَالِدٍ، عَنْ عِكْرِمَةَ، عَنْ عَائِشَةَ
قَالَتْ: اعْتَكَفَتْ مَعَ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ امْرَأَةٌ مِنْ أَزْوَاجِهِ، فَكَانَتْ تَرَى الدَّمَ وَالصُّفْرَةَ وَالطَّسْتُ تَحْتَهَا وَهِيَ تُصَلِّي
