وَعَنْهَا: «أَنَّ اَلنَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَعْتَكِفُ اَلْعَشْرَ اَلْأَوَاخِرَ مِنْ رَمَضَانَ، حَتَّى تَوَفَّاهُ اَللَّهُ، ثُمَّ اعْتَكَفَ أَزْوَاجُهُ مِنْ بَعْدِهِ»
Aishah (RAA) narrated, ‘The Messenger of Allah (sallallahu alayhi wa sallam) used to perform Itikaf during the last ten days of Ramadan until he died. Then his wives used to perform Itikaf after his death.’ Agreed upon.
