The Prophet ﷺ said: A man who cupped and a man who has himself cupped broke their fast. The narrator Shayban said in his version: AbuQilabah told me that AbuAsma' ar-Rahbi told him that Thawban, the client of the Messenger of Allah ﷺ, told him that he heard the Prophet ﷺ say this.  

عَنِ النَّبِيِّ ﷺ قَالَ أَفْطَرَ الْحَاجِمُ وَالْمَحْجُومُ قَالَ شَيْبَانُ أَخْبَرَنِي أَبُو قِلاَبَةَ أَنَّ أَبَا أَسْمَاءَ الرَّحَبِيَّ حَدَّثَهُ أَنَّ ثَوْبَانَ مَوْلَى رَسُولِ اللَّهِ ﷺ أَخْبَرَهُ أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ  

The tradition mentioned above (No. 2361) has also been transmitted by Shaddad ibn Aws through a different chain of narrators. This version adds: While Shaddad ibn Aws was walking along with the Prophet ﷺ....The narrator then transmitted the rest of the tradition to the same effect.  

أَنَّهُ أَخْبَرَهُ أَنَّ شَدَّادَ بْنَ أَوْسٍ بَيْنَمَا هُوَ يَمْشِي مَعَ النَّبِيِّ ﷺ فَذَكَرَ نَحْوَهُ  

The Messenger of Allah ﷺ came to a man at al-Baqi' while he was cupping on the 18th of Ramadan ; he (the Prophet) was holding my hand. Thereupon he said: A man who cups and a man who gets himself cupped break their fast. Abu Dawud said: The narrator Khalid al-Hadhdha' transmitted a similar tradition from Abu Qilabah through a different chain of narrators mentioned by the narrator Ayyub.  

أَنَّ رَسُولَ اللَّهِ ﷺ أَتَى عَلَى رَجُلٍ بِالْبَقِيعِ وَهُوَ يَحْتَجِمُ وَهُوَ آخِذٌ بِيَدِي لِثَمَانَ عَشْرَةَ خَلَتْ مِنْ رَمَضَانَ فَقَالَ أَفْطَرَ الْحَاجِمُ وَالْمَحْجُومُ  

The Prophet ﷺ as saying: A man who cups and a man who gets himself cupped break their fast.  

أَخْبَرَهُ أَنَّ ثَوْبَانَ مَوْلَى رَسُولِ اللَّهِ ﷺ أَخْبَرَهُ أَنَّ النَّبِيَّ ﷺ قَالَ أَفْطَرَ الْحَاجِمُ وَالْمَحْجُومُ  

The Prophet ﷺ as saying: A man who cups and a man who gets himself cupped break their fast. Abu Dawud said: Ibn Thawban transmitted a similar tradition from his father on the authority of Makhul through an chain of narrators mentioned by him.  

عَنِ النَّبِيِّ ﷺ قَالَ أَفْطَرَ الْحَاجِمُ وَالْمَحْجُومُ
