مَا رَوَاهُ زُرْعَةُ عَنِ اَلْمُفَضَّلِ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: «كَانَ أَبِي عَلَيْهِ اَلسَّلاَمُ يَفْصِلُ مَا بَيْنَ شَعْبَانَ وَ شَهْرِ رَمَضَانَ بِيَوْمٍ وَ كَانَ عَلِيُّ بْنُ اَلْحُسَيْنِ عَلَيْهِمَا اَلسَّلاَمُ يَصِلُ مَا بَيْنَهُمَا وَ يَقُولُ «صَوْمُ شَهْرَيْنِ مُتَتَابِعَيْنِ تَوْبَةٌ مِنَ اَللَّهِ» ».
