Sahih Muslim, 4040

Rapporté par Humaid : Anas رضي الله عنه a dit : Le Messager d’Allah ﷺ a fait venir un jeune praticien de la saignée de chez nous. Il lui a fait une saignée et a ordonné qu’on lui donne un sa’, ou un mudd, ou deux mudds de blé. On a dit que le prix était élevé, alors une réduction a été faite

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
