(11) باب حِلِّ أُجْرَةِ الْحِجَامَةِ
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.
