7ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَسَنِ عَنْ أَحْمَدَ بْنِ صَبِيحٍ عَنْ عَنْبَسَةَ الْعَابِدِ قَالَ قُبِضَ النَّبِيُّ (صلَّى اللهُ عَلَيْهِ وَآلِه) عَلَى صَوْمِ شَعْبَانَ وَرَمَضَانَ وَثَلاثَةِ أَيَّامٍ فِي كُلِّ شَهْرٍ أَوَّلِ خَمِيسٍ وَأَوْسَطِ أَرْبِعَاءَ وَآخِرِ خَمِيسٍ وَكَانَ أَبُو جَعْفَرٍ وَأَبُو عَبْدِ الله (عَلَيْهِ السَّلاَم) يَصُومَانِ ذَلِكَ.
