4ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَفْصِ بْنِ الْبَخْتَرِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ كُنَّ نِسَاءُ النَّبِيِّ (صلَّى اللهُ عَلَيْهِ وَآلِه) إِذَا كَانَ عَلَيْهِنَّ صِيَامٌ أَخَّرْنَ ذَلِكَ إِلَى شَعْبَانَ كَرَاهَةَ أَنْ يَمْنَعْنَ رَسُولَ الله (صلَّى اللهُ عَلَيْهِ وَآلِه) فَإِذَا كَانَ شَعْبَانُ صُمْنَ وَكَانَ رَسُولُ الله (صلَّى اللهُ عَلَيْهِ وَآلِه) يَقُولُ شَعْبَانُ شَهْرِي.
4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hafs ibn al-Bakhtariy who has said the following: “Abu ‘ Abd Allah (a.s.), has said that wives of the Holy Prophet, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, when required to fast, would wait up to the month of Sha‘ban, due to anticipation that he may forbid them. In the month of Sha‘ban they would fast and the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘Sha‘ban is my month.’”
