In-book no 3911حَدَّثَنَا أَحْمَدُ بْنُ الْحَسَنِ بْنِ خِرَاشٍ، حَدَّثَنَا شَبَابَةُ، حَدَّثَنَا شُعْبَةُ، عَنْ حُمَيْدٍ، قَالَ سَمِعْتُ أَنَسًا، يَقُولُ دَعَا النَّبِيُّ صلى الله عليه وسلم غُلاَمًا لَنَا حَجَّامًا فَحَجَمَهُ فَأَمَرَ لَهُ بِصَاعٍ أَوْ مُدٍّ أَوْ مُدَّيْنِ وَكَلَّمَ فِيهِ فَخُفِّفَ عَنْ ضَرِيبَتِهِ .
Humaid reported Anas (Allah be pleased with him) having said this: Allah's Apostle (ﷺ) called for young cupper belonging to us. He capped him and he (the Holy Prophet) commanded that he should be paid one sa' or one mudd or two mudds (of wheat). It was said (that charges were high) and a reduction was made in the charges.
