It is narrated from Sayyiduna Usama bin Sharik (may Allah be pleased with him) that he said: I was present when the Bedouins were asking the Prophet (peace and blessings of Allah be upon him) questions: Is there any harm for us in doing such and such a thing? Is there any sin for us in doing such and such a thing? So the Messenger of Allah (peace and blessings of Allah be upon him) said: "O servants of Allah! Allah has removed hardship/difficulty, except for the one who cuts off a portion from his brother’s honor; so this is the person who has sinned and is destroyed." They said: O Messenger of Allah! Should we seek medical treatment? So he (peace and blessings of Allah be upon him) said: "Seek medical treatment, for Allah has sent down a cure for every disease He has sent down, except death." They said: O Messenger of Allah! What is the best thing that has been given to a servant? He (peace and blessings of Allah be upon him) said: "Good character."

Sayyiduna Usamah bin Shuraik (may Allah be pleased with him) narrated: I was present with the Bedouins when they were asking questions to the Messenger of Allah (peace and blessings be upon him). Then the narrator mentioned the same (incident), and in it, he narrated this addition: When they stood before him (the Prophet, peace be upon him), they began to kiss his blessed hand. The narrator said: I touched his blessed hand with mine, and it was more fragrant than musk.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "If there is any good in the treatments you use, it is in the bloodletting done by the cupper."
