حَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا مَرْوَانُ، - يَعْنِي الْفَزَارِيَّ - عَنْ حُمَيْدٍ، قَالَ سُئِلَ أَنَسٌ عَنْ كَسْبِ الْحَجَّامِ، فَذَكَرَ بِمِثْلِهِ غَيْرَ أَنَّهُ قَالَ ‏ "‏ إِنَّ أَفْضَلَ مَا تَدَاوَيْتُمْ بِهِ الْحِجَامَةُ وَالْقُسْطُ الْبَحْرِيُّ وَلاَ تُعَذِّبُوا صِبْيَانَكُمْ بِالْغَمْزِ ‏" ‏ ‏.‏
