It was narrated from Ibn 'Abbas that :
the Prophet ﷺ was treated with cupping and he gave him (the cupper) his wages. Ibn Abu 'Umar was alone in narrating it. That was said by Ibn Majah. [1]

حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي عُمَرَ الْعَدَنِيُّ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ ابْنِ طَاوُسٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ ـ ﷺ ـ احْتَجَمَ وَأَعْطَاهُ أَجْرَهُ . قَالَ ابْنُ مَاجَهْ تَفَرَّدَ بِهِ ابْنُ أَبِي عُمَرَ وَحْدَهُ .
