Ibn Abbas said:

"The Prophet (ﷺ) had cupping performed between the two veins in the neck and between the shoulders. He also gave the cupper his fee, which he would not have done if cupping had been unlawful.”

حَدَّثَنَا هَارُونُ بْنُ إِسْحَاقَ الْهَمْدَانِيُّ، قَالَ‏:‏ حَدَّثَنَا عَبْدَةُ، عَنْ سُفْيَانَ الثَّوْرِيِّ، عَنْ جَابِرٍ، عَنِ الشَّعْبِيِّ، عَنِ ابْنِ عَبَّاسٍ، قَالَ‏:‏ إِنَّ النَّبِيَّ صلى الله عليه وسلم احْتَجَمَ فِي الأَخْدَعَيْنِ، وَبَيْنَ الْكَتِفَيْنِ، وَأَعْطَى الْحَجَّامَ أَجْرَهُ، وَلَوْ كَانَ حَرَامًا لَمْ يُعْطِهِ‏.‏
