Sunan an-Nasa'i 2183
It was narrated that 'Abdullah bin Shaqiq said:
""I asked 'Aishah about the fasting of the Messenger of Allah. She said: 'The Messenger of Allah used to fast until we said that he is going to fast (continually), and he used not to fast until we said: he is not going to fast. And he did not fast for a whole month from the time he came to Al-Madinah, apart from Ramadan."' '
أَخْبَرَنَا مُحَمَّدُ بْنُ أَحْمَدَ بْنِ أَبِي يُوسُفَ الصَّيْدَلاَنِيُّ، - حَرَّانِيٌّ - قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ سَلَمَةَ، عَنْ هِشَامٍ، عَنِ ابْنِ سِيرِينَ، عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ، عَنْ عَائِشَةَ، قَالَ سَأَلْتُهَا عَنْ صِيَامِ، رَسُولِ اللَّهِ ﷺ قَالَتْ كَانَ رَسُولُ اللَّهِ ﷺ يَصُومُ حَتَّى نَقُولَ قَدْ صَامَ وَيُفْطِرُ حَتَّى نَقُولَ قَدْ أَفْطَرَ وَلَمْ يَصُمْ شَهْرًا تَامًّا مُنْذُ أَتَى الْمَدِينَةَ إِلاَّ أَنْ يَكُونَ رَمَضَانُ .
