Anas bin Maalik (may Allah be pleased with him) reports:
"Messenger of Allah ﷺ took treatment of cupping on the back of his leg at Milal (a place about seventeen miles-27 km-from Madinah Munawwarah in the direction of Makkah) while he was in the state of ihraam".

حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، قَالَ: أَنْبَأَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ: أَنَّ رَسُولَ اللهِ ﷺ احْتَجَمَ وَهُوَ مُحْرِمٌ بَمَلَلٍ عَلَى ظَهْرِ الْقَدَمِ.
