Narrated Anas ibn Malik: The Messenger of Allah (ﷺ) had himself cupped on the surface of his foot because of a pain in it while he was in the sacred state (wearing ihram). Abu Dawud said: I heard Ahmad say: "Ibn Abi 'Arubah narrated it in Mursal form". Meaning from Qatadah.

حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم احْتَجَمَ وَهُوَ مُحْرِمٌ عَلَى ظَهْرِ الْقَدَمِ مِنْ وَجَعٍ كَانَ بِهِ ‏.‏ قَالَ أَبُو دَاوُدَ سَمِعْتُ أَحْمَدَ قَالَ ابْنُ أَبِي عَرُوبَةَ أَرْسَلَهُ يَعْنِي عَنْ قَتَادَةَ ‏.‏
