Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: "Allah, the Exalted, has not sent down any disease (upon His servants) except that He has also sent down its cure."

Narrated by Sayyiduna Ibn Abbas (may Allah be pleased with them both) from the Noble Prophet (peace and blessings of Allah be upon him) that he said: "There is healing (from illness) in three things: (1) drinking honey, (2) cupping, (3) cauterization with fire (but) I forbid my Ummah from cauterization."

Narrated Abu Sa'id Al-Khudri (may Allah be pleased with him):
A man came to the Prophet (peace and blessings of Allah be upon him) and said, "My brother has a stomach disorder (i.e., he has diarrhea)." The Prophet (peace be upon him) said, "Make him drink honey." So he went and made him drink it. Then he came back and said, "He did not get better." The Prophet (peace be upon him) said, "Make him drink honey again." He went and made him drink it. Then he returned and said, "He still did not get better, and I have done everything." The Prophet (peace be upon him) said, "Allah has spoken the truth (that 'in honey there is healing for people'), and your brother's stomach has lied. So let him drink honey." He kept giving him honey until he was cured.

Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) says: I heard the Messenger of Allah (peace and blessings be upon him) say: "Indeed, this black seed (black cumin) is a cure for every disease except as-sam." I asked, "What is as-sam?" He (peace and blessings be upon him) replied: "Death."

Lady Umm Qais bint Mihsan (may Allah be pleased with her) says: I heard the Noble Prophet (peace and blessings of Allah be upon him) say: "You should use Indian aloeswood (oud al-hindi), for it is a cure for seven diseases. For 'uzrah (throat swelling, i.e., diphtheria), it is inserted into the nose, and for pain in the side, it is placed in the mouth." (And the rest of the hadith has already been mentioned.)

The hadith of Sayyiduna Anas (may Allah be pleased with him) that "Abu Taybah performed cupping for the Messenger of Allah (peace and blessings be upon him)." (In the Book: Regarding Buying and Selling... Chapter: Statement about the Profession of the Cupper... this hadith has already been mentioned, and at the end of this hadith it is stated that) Indeed, the Messenger of Allah (peace and blessings be upon him) said: "Cupping and Indian costus are among your best remedies." And he said: "Do not cause pain to your children by pressing the palate in cases of throat disease (i.e., diphtheria), rather use costus."

Narrated Ibn Abbas (may Allah be pleased with them both): The Messenger of Allah (peace and blessings of Allah be upon him) said: "The previous nations were presented before me. The prophets passed by, some with one man, some with two men, some with a small group from their nation, and there was a prophet with whom there was not even a single follower. Then a large group was shown to me, and I asked: 'Whose nation is this? Is this my nation?' I was told: 'This is Musa (Moses) and his nation.' Then I was told: 'Look at the sky.' (So I looked and saw) a huge group had covered the horizon. Then I was told: 'Look at the other side of the sky.' I saw that indeed a very large group was covering the horizon. Then I was told: 'This is your nation, and among them seventy thousand will enter Paradise without reckoning or punishment.' After saying this, the Messenger of Allah (peace and blessings of Allah be upon him) went into (his chamber) and did not clarify to the people who those (seventy thousand) would be. (Upon this) the people began to discuss. They said: 'We believed in Allah and obeyed His Messenger (peace and blessings of Allah be upon him), so we are those people, or it will be our children who were born in the era of Islam, because we were born in the era of ignorance.' This news reached the Prophet (peace and blessings of Allah be upon him). The Messenger of Allah (peace and blessings of Allah be upon him) came out and said: 'They are those who do not seek ruqyah (spiritual healing), nor do they believe in bad omens, nor do they cauterize (themselves for treatment), but they put their trust only in their Lord.' Ukasha bin Mihsan (may Allah be pleased with him) stood up and said: 'O Messenger of Allah! Am I among them?' He said: 'Yes, you are among them.' Another man stood up and began to say: 'Am I also among them?' The Prophet (peace and blessings of Allah be upon him) said: 'Ukasha has preceded you.'"

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) used to say: "The illness of one does not infect another, taking bad omens, considering the owl as a bad omen, and considering the month of Safar as unlucky—all these are baseless thoughts. However, one should keep away from a leper as much as one keeps away from a lion." (Benefit: This is not because the disease of the leper is contagious, but rather, the instruction to keep distance is given so that it may be that Allah had decreed his illness by coincidence, and he became ill. Now, if someone thinks in his heart that he got the disease because he sat with so-and-so, then this is a sin. To save from falling into this sin, as a preventive measure, keeping distance has been advised.)

Sayyiduna Abu Hurairah (may Allah be pleased with him) in another narration says that the Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no contagious disease, nor is there any (evil omen in the month of) Safar, nor is the owl (a sign of bad luck)." Upon hearing this, a Bedouin said to the Messenger of Allah (peace and blessings of Allah be upon him): "Then why is it that my camels are as lively and active as deer in the sandy desert, but when a mangy camel comes among them and mingles with them, they all become mangy because of it?" The Prophet (peace and blessings of Allah be upon him) said: "Then from where did the first one get the mange?"

Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings of Allah be upon him) had permitted the family of an Ansari to perform ruqyah (spiritual healing) for scorpion stings and ear pain. And due to pain in my ribs, I was cauterized during the lifetime of the Prophet (peace and blessings of Allah be upon him), and Abu Talha, Anas bin Nadr, and Zaid bin Thabit (may Allah be pleased with them) were present, and Abu Talha (may Allah be pleased with him) performed the cauterization.
