أَخْبَرَنَا مُحَمَّدُ بْنُ عِيسَى ، حَدَّثَنَا أَبُو عَوَانَةَ ، عَنْ أَبِي بِشْرٍ ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ ، عَنْ ابْنِ عَبَّاسٍ ، قَالَ :" مَا صَامَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ شَهْرًا كَامِلًا غَيْرَ رَمَضَانَ، وَإِنْ كَانَ لَيَصُومُ إِذَا صَامَ حَتَّى يَقُولَ الْقَائِلُ : لَا وَاللَّهِ لَا يُفْطِرُ، وَيُفْطِرُ إِذَا أَفْطَرَ حَتَّى يَقُولَ الْقَائِلُ : لَا وَاللَّهِ لَا يَصُومُ "

Muhammad bin Issa told us, Abu Awanah told us, on the authority of Abu Bishr, on the authority of Sa`id bin Jubayr, on the authority of Ibn Abbas, he said: “The Prophet did not fast May God’s prayers and peace be upon him for a full month other than Ramadan, although he may fast when he fasts until the one who says: No, by God, he does not break his fast, and he breaks his fast when He broke his fast until someone said: No, by God, he does not fast.”
