Abdullah b. 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.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ سَعِيدٍ الْجُرَيْرِيِّ، عَنْ عَبْدِ اللَّهِ، بْنِ شَقِيقٍ قَالَ قُلْتُ لِعَائِشَةَ رضى الله عنها هَلْ كَانَ النَّبِيُّ ﷺ يَصُومُ شَهْرًا مَعْلُومًا سِوَى رَمَضَانَ قَالَتْ وَاللَّهِ إِنْ صَامَ شَهْرًا مَعْلُومًا سِوَى رَمَضَانَ حَتَّى مَضَى لِوَجْهِهِ وَلاَ أَفْطَرَهُ حَتَّى يُصِيبَ مِنْهُ .
