حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا أَيُّوبُ، عَنْ أَبِي قِلاَبَةَ، عَنْ أَبِي الأَشْعَثِ، عَنْ شَدَّادِ بْنِ أَوْسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَتَى عَلَى رَجُلٍ بِالْبَقِيعِ وَهُوَ يَحْتَجِمُ وَهُوَ آخِذٌ بِيَدِي لِثَمَانَ عَشْرَةَ خَلَتْ مِنْ رَمَضَانَ فَقَالَ ‏"‏ أَفْطَرَ الْحَاجِمُ وَالْمَحْجُومُ ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ وَرَوَى خَالِدٌ الْحَذَّاءُ عَنْ أَبِي قِلاَبَةَ بِإِسْنَادِ أَيُّوبَ مِثْلَهُ ‏.‏

Narrated Shaddad b. Aws: The Messenger of Allah (PBUH) 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. Translation Not Available
