حَدَّثَنَا عَاصِمُ بْنُ يُوسُفَ ، حَدَّثَنَا أَبُو بَكْرِ بْنِ عَيَّاشٍ ، عَنْ أَبِي حَصِينٍ ، عَنْ أَبِي صَالِحٍ ، عَنْ أَبِي هُرَيْرَةَ ، قَالَ : " كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَيَعْتَكِفُ الْعَشْرَ الْأَوَاخِرَ، فَلَمَّا كَانَ الْعَامُ الَّذِي قُبِضَ فِيهِ، اعْتَكَفَ عِشْرِينَ يَوْمًا "
