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.‏

Narrated Ibn `Abbas

Once the Prophet (ﷺ) got his blood out (medically) and paid that person who had done it. If it had been illegal, the Prophet (ﷺ) would not have paid him.
