The Prophet (peace and blessings be upon him) replied: The one who has the best character. He then said: O Messenger of Allah! Can we seek medical treatment?

(Second chain) Shu’bah, from Ziyad bin ‘Ilaqah, and he from Sayyiduna Usamah bin Sharik (may Allah be pleased with him), narrates that he said: I came to the Noble Prophet (peace and blessings be upon him), while his noble companions were also present with him. They were sitting so respectfully as if birds were perched on their heads. I greeted the Prophet (peace and blessings be upon him) and sat down there. A Bedouin came and asked the Prophet (peace and blessings be upon him): O Messenger of Allah! Can we seek treatment? The Prophet (peace and blessings be upon him) said: Yes! Seek treatment or get treated. Indeed, Allah Almighty has created a cure for every disease He has created, except for old age (and according to one narration, also death). When Sayyiduna Usamah (may Allah be pleased with him) became old, he used to say: Can you treat me now? Besides this, the Bedouins asked the Prophet (peace and blessings be upon him): Is there any harm in such-and-such thing? The Prophet (peace and blessings be upon him) said: O servants of Allah! Allah Almighty has not placed any hardship in the religion, except in the matter where a Muslim commits oppression; that is hardship, that is destruction. They said: O Messenger of Allah! What is the best thing that has been given to people? The Prophet (peace and blessings be upon him) said: Good character.

It is narrated from a Companion that the Noble Prophet, peace and blessings be upon him, visited an Ansari man who was wounded.

Does medicine benefit?" The Prophet, peace and blessings be upon him, said: "Glory be to Allah! For every disease that exists on the earth, Allah Almighty has also created its cure."

‘Ata bin Sa’ib narrates that I came to ‘Abd al-Rahman, and he was branding a slave. I said: Do you brand him? He said: Yes, this is the Arabs’ method of treatment. It is narrated from Sayyiduna ‘Abdullah bin Mas‘ud (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Allah Almighty has not created any disease except that He has also sent down its cure. Whoever among you is ignorant of it, is ignorant of it, and whoever has come to know it, has come to know it.

Sayyida Aisha (may Allah be pleased with her) narrates that the Noble Prophet (peace and blessings be upon him) said: Applying heat with a cloth is better than cauterization; instilling drops in the nose is a better method of treatment than applying medicine by inserting a finger into the throat; and administering medicine from one side of the mouth is a better method of treatment than blowing into the throat.

Abu Khuzamah, who is from Banu Harith bin Sa’d bin Maryam, narrates: O Messenger of Allah!

The Noble Prophet (peace and blessings be upon him) said: These too are a part of Allah’s decree.
