Hadith 297

Abdullah ibn Shaqiq said: "I asked 'A'isha (may Allah the Exalted be well pleased with her) about the fasting of Allah’s Messenger (Allah bless him and give him peace). She said: “He used to fast until we would say: ‘He has fasted,’ and he used to break fast until we would say: ‘He has broken fast.’” She also said: “Allah’s Messenger (Allah bless him and give him peace) did not fast for a whole month after arriving in Medina, with the exception of Ramadan.’

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ‏:‏ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ عَبْدِ اللهِ بْنِ شَقِيقٍ، قَالَ‏:‏ سَأَلْتُ عَائِشَةَ، عَنْ صِيَامِ رَسُولِ اللهِ صلى الله عليه وسلم، قَالَتْ‏:‏ كَانَ يَصُومُ حَتَّى نَقُولَ قَدْ صَامَ، وَيُفْطِرُ حَتَّى نَقُولَ قَدْ أَفْطَرَ قَالَتْ‏:‏ وَمَا صَامَ رَسُولُ اللهِ صلى الله عليه وسلم، شَهْرًا كَامِلا مُنْذُ قَدِمَ الْمَدِينَةَ إِلا رَمَضَانَ‏.‏
