حَدَّثَنَا عَبْدُ اللَّهِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا أَبُو بَکْرٍ عَنْ أَبِي حَصِينٍ عَنْ أَبِي صَالِحٍ عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ کَانَ النَّبِيُّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ يَعْتَکِفُ فِي کُلِّ رَمَضَانٍ عَشْرَةَ أَيَّامٍ فَلَمَّا کَانَ الْعَامُ الَّذِي قُبِضَ فِيهِ اعْتَکَفَ عِشْرِينَ يَوْمًا
