٤ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ عَنْ أَبِي أَيُّوبَ عَنْ أَبِي عُبَيْدَةَ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلاَم) قَالَ الْمُعْتَكِفُ لا يَشَمُّ الطِّيبَ وَلا يَتَلَذَّذُ بِالرَّيْحَانِ وَلا يُمَارِي وَلا يَشْتَرِي وَلا يَبِيعُ قَالَ وَمَنِ اعْتَكَفَ ثَلاثَةَ أَيَّامٍ فَهُوَ يَوْمَ الرَّابِعِ بِالْخِيَارِ إِنْ شَاءَ زَادَ ثَلاثَةَ أَيَّامٍ أُخَرَ وَإِنْ شَاءَ خَرَجَ مِنَ الْمَسْجِدِ فَإِنْ أَقَامَ يَوْمَيْنِ بَعْدَ الثَّلاثَةِ فَلا يَخْرُجُ مِنَ الْمَسْجِدِ حَتَّى يُتِمَّ ثَلاثَةَ أَيَّامٍ أُخَرَ.
