Sahih Muslim , Book 10, Hadith 3834 (USC-MSA) ⓘ
Ibn 'Abbas (Allah be pleased with them) reported: The slave of Banu Bayada cupped Allah's Apostle and he gave him his wages, and talked to his master and he reduced the charges, and if this earning was unlawful Allah's Apostle would not have given it.
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَعَبْدُ بْنُ حُمَيْدٍ، - وَاللَّفْظُ لِعَبْدٍ - قَالاَ أَخْبَرَنَا عَبْدُ، الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ، عَنْ عَاصِمٍ، عَنِ الشَّعْبِيِّ، عَنِ ابْنِ عَبَّاسٍ، قَالَ حَجَمَ النَّبِيَّ صلى الله عليه وسلم عَبْدٌ لِبَنِي بَيَاضَةَ فَأَعْطَاهُ النَّبِيُّ صلى الله عليه وسلم أَجْرَهُ وَكَلَّمَ سَيِّدَهُ فَخَفَّفَ عَنْهُ مِنْ ضَرِيبَتِهِ وَلَوْ كَانَ سُحْتًا لَمْ يُعْطِهِ النَّبِيُّ صلى الله عليه وسلم .
