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 " .

Then (the above-mentioned hadith was reported but with this addition) that he said: The best treatment which you get is cupping. or aloeswood and do not torture your children by pressing their uvula.
