حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا هِشَامٌ عَنْ مُحَمَّدٍ عَنِ ابْنِ عَبَّاسٍ قَالَ احْتَجَمَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَعْطَى الْحَجَّامَ أَجْرَهُ وَلَوْ كَانَ سُحْتًا لَمْ يُعْطِهِ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
مسند امام احمد بن حنبل · Hadith 3085
It was narrated that Ibn Abbas (RA) said: The Messenger of Allah (PBUH) was treated with cupping and he gave the cupper his fee. If it was haram , the Messenger of Allah (PBUH) would not have given it to him.
