حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَی حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ عَنْ حَمَّادِ بْنِ سَلَمَةَ عَنْ ثَابِتٍ عَنْ أَبِي رَافِعٍ عَنْ أُبَيِّ بْنِ کَعْبٍ أَنَّ النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ کَانَ يَعْتَکِفُ الْعَشْرَ الْأَوَاخِرَ مِنْ رَمَضَانَ فَسَافَرَ عَامًا فَلَمَّا کَانَ مِنْ الْعَامِ الْمُقْبِلِ اعْتَکَفَ عِشْرِينَ يَوْمًا
