[Machine] The Prophet ﷺ passed by a man who was getting bloodletting done on the seventeenth day of Ramadan, so he said, "The one who gets bloodletting done and the one who does it for others have broken their fast." Abu Muhammad Al-Hasan bin Muhammad bin Ishaq Al-Isfaraini told us, Muhammad bin Ahmad bin Al-Bara' told us, 'Ali bin Al-Madinani said, "Shaddad bin Aws narrated from the Messenger of Allah ﷺ that he saw a man getting bloodletting done in Ramadan." Aasim Al-Ahwal narrated it from Abu Qilabah, who narrated it from Abu Al-Ash'ath, and Yahya bin Abi Kathir narrated it from Abu Qilabah, who narrated it from Abu Asma', who narrated it from Thawban. "I do not see the authenticity of the two narrations except as Sahih, for it is possible that he heard it from all of them." As for the permission for cupping for the fasting person, it was reported by Muhammad ibn Isma'il Al-Bukhari in Al-Jami'al-Sahih.  

أَنَّ النَّبِيَّ ﷺ مَرَّ بِرَجُلٍ يَحْتَجِمُ فِي سَبْعَ عَشْرَةَ مِنْ رَمَضَانَ فَقَالَ «أَفْطَرَ الْحَاجِمُ وَالْمَحْجُومُ» حَدَّثَنَا أَبُو مُحَمَّدٍ الْحَسَنُ بْنُ مُحَمَّدِ بْنِ إِسْحَاقَ الْإِسْفَرَائِنِيُّ ثنا مُحَمَّدُ بْنُ أَحْمَدَ بْنِ الْبَرَاءِ ثنا عَلِيُّ بْنُ الْمَدِينِيِّ قَالَ حَدِيثُ شَدَّادِ بْنِ أَوْسٍ عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ رَأَى رَجُلًا يَحْتَجِمُ فِي رَمَضَانَ رَوَاهُ عَاصِمٌ الْأَحْوَلُ عَنْ أَبِي قِلَابَةَ عَنْ أَبِي الْأَشْعَثِ وَرَوَاهُ يَحْيَى بْنُ أَبِي كَثِيرٍ عَنْ أَبِي قِلَابَةَ عَنْ أَبِي أَسْمَاءَ عَنْ ثَوْبَانَ «وَلَا أَرَى الْحَدِيثَيْنِ إِلَّا صَحِيحَيْنِ فَقَدْ يُمْكِنُ أَنْ يَكُونَ سَمِعَهُ مِنْهُمَا جَمِيعًا» فَأَمَّا رُخْصَةُ الْحِجَامَةِ لِلصَّائِمِ فَقَدْ أَخْرَجَهُ مُحَمَّدُ بْنُ إِسْمَاعِيلَ الْبُخَارِيُّ فِي الْجَامِعِ الصَّحِيحِ
