Sahih Muslim Book - 22, Hadith - 4042

حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ وَعَبْدُ بْنُ حُمَيْدٍ - وَاللَّفْظُ لِعَبْدٍ - قَالاَ أَخْبَرَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ عَنْ عَاصِمٍ عَنِ الشَّعْبِىِّ عَنِ ابْنِ عَبَّاسٍ قَالَ حَجَمَ النَّبِىَّ -صلى الله عليه وسلم- عَبْدٌ لِبَنِى بَيَاضَةَ فَأَعْطَاهُ النَّبِىُّ -صلى الله عليه وسلم- أَجْرَهُ وَكَلَّمَ سَيِّدَهُ فَخَفَّفَ عَنْهُ مِنْ ضَرِيبَتِهِ وَلَوْ كَانَ سُحْتًا لَمْ يُعْطِهِ النَّبِىُّ -صلى الله عليه وسلم-.

It was narrated that Ibn 'Abbas said: "The Prophet was treated with cupping by a slave of Banu Baiadah, and the Prophet (s.a.w) gave him his wages, and spoke to his master, who reduced his (the master's) portion of his earnings. If it were unlawful the Prophet (s.a.w) would not have given him anything."
