Cupping and vomiting in Saum (fast)

وَقَالَ لِي يَحْيَى بْنُ صَالِحٍ حَدَّثَنَا مُعَاوِيَةُ بْنُ سَلاَّمٍ، حَدَّثَنَا يَحْيَى، عَنْ عُمَرَ بْنِ الْحَكَمِ بْنِ ثَوْبَانَ، سَمِعَ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ إِذَا قَاءَ فَلاَ يُفْطِرُ، إِنَّمَا يُخْرِجُ وَلاَ يُولِجُ‏.‏ وَيُذْكَرُ عَنْ أَبِي هُرَيْرَةَ أَنَّهُ يُفْطِرُ‏.‏ وَالأَوَّلُ أَصَحُّ‏.‏ وَقَالَ ابْنُ عَبَّاسٍ وَعِكْرِمَةُ الصَّوْمُ مِمَّا دَخَلَ، وَلَيْسَ مِمَّا خَرَجَ‏.‏ وَكَانَ ابْنُ عُمَرَ ـ رضى الله عنهما ـ يَحْتَجِمُ، وَهُوَ صَائِمٌ، ثُمَّ تَرَكَهُ، فَكَانَ يَحْتَجِمُ بِاللَّيْلِ‏.‏ وَاحْتَجَمَ أَبُو مُوسَى لَيْلاً‏.‏ وَيُذْكَرُ عَنْ سَعْدٍ وَزَيْدِ بْنِ أَرْقَمَ وَأُمِّ سَلَمَةَ احْتَجَمُوا صِيَامًا‏.‏ وَقَالَ بُكَيْرٌ عَنْ أُمِّ عَلْقَمَةَ كُنَّا نَحْتَجِمُ عِنْدَ عَائِشَةَ فَلاَ تَنْهَى‏.‏ وَيُرْوَى عَنِ الْحَسَنِ عَنْ غَيْرِ وَاحِدٍ مَرْفُوعًا فَقَالَ أَفْطَرَ الْحَاجِمُ وَالْمَحْجُومُ‏.‏ وَقَالَ لِي عَيَّاشٌ حَدَّثَنَا عَبْدُ الأَعْلَى حَدَّثَنَا يُونُسُ عَنِ الْحَسَنِ مِثْلَهُ‏.‏ قِيلَ لَهُ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ نَعَمْ‏.‏ ثُمَّ قَالَ اللَّهُ أَعْلَمُ‏.‏Narrated Abu Hurairah رضي الله عنه: “If a person observing Saum (fast) vomits, that does not break his Saum (fast), for while he vomits he expels something and does not swallow anything.” It is mentioned from Abu Hurairah that vomiting breaks the Saum (fast), but the former narration is more authentic. Ibn ‘Abbas and ‘Ikrima said, “Observing Saum (fast) means to stop taking food in, not taking it out.” And Ibn ‘Umar رضي الله عنهما used to be cupped while he was observing Saum (fast) but later on he abandoned it and began to be cupped at night. Abu Musa was cupped at night. It is narrated that Sa‘d, Zaid bin Arqam and Umm Salama were cupped while observing Saum (fast). Bukair said: Umm ‘Alqama said: “We used to be cupped [during observing Saum (fast)] in ‘Aisha’s presence and she did not object. Al-Hasan and others narrate on the authority of the Prophet ﷺ, “The cupping and the cupped persons break Saum (fast) on practising this operation while Saum (fast).” ‘Aishah told me (Al-Bukhari) that ‘Abdul-A‘la narrated from Yunus from Al-Hasan as above. Somebody asked him, “Was that statement reported from the Prophet ﷺ?” He replied, “Yes,” and then added, “Allah knows better.”
