حَدَّثَنَا يَحْيَى بْنُ يَحْيَى ، أَخْبَرَنَا يَزِيدُ بْنُ زُرَيْعٍ ، عَنْ سَعِيدٍ الْجُرَيْرِيِّ ، عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ ، قَالَ : قُلْتُ لِعَائِشَةَ رَضِيَ اللَّهُ عَنْهَا : هَلْ كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَصُومُ شَهْرًا مَعْلُومًا سِوَى رَمَضَانَ ؟ قَالَتْ : " وَاللَّهِ إِنْ صَامَ شَهْرًا مَعْلُومًا سِوَى رَمَضَانَ ، حَتَّى مَضَى لِوَجْهِهِ ، وَلَا أَفْطَرَهُ حَتَّى يُصِيبَ مِنْهُ " .
Abdullah bin Shaqiq reported: I said to'A'isha (Allah be pleased with her): Did the Apostle of Allah (ﷺ) observe fast for full one month besides Ramadan? She said: I do not know of any month in which he fasted through-out, but that of the month of Ramadan and (the month) in which he did not fast at all, till he ran the course of his life.
