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. (Using translation from Abū Dāʾūd 2369)
أَنَّ النَّبِيَّ ﷺ أَتَى عَلَى رَجُلٍ وَهُوَ يَحْتَجِمُ بِالْبَقِيعِ فِي ثَمَانِ عَشْرَةَ خَلَتْ مِنْ رَمَضَانَ فَقَالَ «أَفْطَرَ الْحَاجِمُ وَالْمَحْجُومُ»
