[Machine] The Messenger of Allah ﷺ used to observe Iʿtikāf (spiritual retreat) during the last ten days of Ramadan until Allah took him. Then his wives observed Iʿtikāf after him. Abu ʿAbdul-Raḥmān narrated it from Al-Laith from Az-Zuhrī from Saʿīd as a Mursal Hadith.
أَنَّ رَسُولَ اللهِ ﷺ كَانَ «يَعْتَكِفُ الْعَشْرَ الْأَوَاخِرَ مِنْ رَمَضَانَ حَتَّى تَوَفَّاهُ اللهُ ثُمَّ اعْتَكَفَ أَزْوَاجُهُ مِنْ بَعْدِهِ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ رَوَاهُ اللَّيْثُ عَنِ الزُّهْرِيِّ عَنْ سَعِيدٍ مُرْسَلًا
