باب ذِكْرِ الْحَجَّامِ
Sahih al-Bukhari 2102

Narrated Anas bin Malik:

Abu Taiba cupped Allah's Messenger (ﷺ) so he ordered that he be paid one Sa of dates and ordered his masters to reduce his tax (as he was a slave and had to pay a tax to them).

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ حُمَيْدٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ حَجَمَ أَبُو طَيْبَةَ رَسُولَ اللَّهِ صلى الله عليه وسلم فَأَمَرَ لَهُ بِصَاعٍ مِنْ تَمْرٍ، وَأَمَرَ أَهْلَهُ أَنْ يُخَفِّفُوا مِنْ خَرَاجِهِ‏.‏
