Aswad bin Yazid says that I asked Hazrat Aisha (may Allah be pleased with her) about reciting incantations (ruqyah) for the bite of a poisonous creature, so she said that the Prophet Muhammad (peace and blessings be upon him) permitted reciting incantations for the bite of every poisonous creature.

Hazrat Aisha (may Allah be pleased with her) narrated that the Prophet Muhammad (peace and blessings be upon him) used to recite this supplication for a sick person (by placing his index finger on the ground): "With the help of Allah's name, with the soil of our land, and with the saliva of one of us, so that our patient may be cured by the command of our Lord."

Hazrat Aisha (may Allah be pleased with her) narrated that the Messenger of Allah (peace and blessings be upon him) ordered me, or (she narrated in this way that) the Messenger of Allah (peace and blessings be upon him) ordered that when afflicted by the evil eye, recite the Mu'awwidhatain (Surah Al-Falaq and Surah An-Naas) and perform ruqyah (spiritual healing) with them.

Narrated Umm Salamah (may Allah be pleased with her): The Prophet (peace and blessings of Allah be upon him) saw a girl in her house whose face had black spots (due to the evil eye). The Prophet (peace and blessings of Allah be upon him) said, "Perform ruqyah for her, for she has been affected by the evil eye."

Hazrat Abu Sa'id Khudri (may Allah be pleased with him) narrated that some companions (may Allah be pleased with them) of the Prophet (peace and blessings of Allah be upon him) were on a journey. During the journey, they stopped at an Arab tribe. The companions wanted the people of the tribe to host them, but they refused to host them and clearly declined. Coincidentally, the chief of that tribe was bitten by a snake. The people of the tribe tried everything, but their chief did not recover. One of their men said, "Let us go and ask those people who have come and stopped here. Perhaps they have something for incantation and healing." So the people of the tribe came to them and said, "Brothers! Our chief has been bitten by a snake. We have tried every possible means for him, but nothing has worked. Do you have anything for incantation?" One of the companions said, "By Allah! I will perform incantation on him, but we had asked you for hospitality and you refused. Therefore, I will not perform the incantation without a fee." Eventually, they agreed on a flock of sheep as payment. That companion went there and recited 'Alhamdulillahi Rabbil 'Alamin' repeatedly as an incantation. It seemed as if someone's ropes had been untied. The chief stood up and began to walk, with no sign of pain or discomfort remaining. It is narrated that then they paid the agreed fee to the companions. Someone said, "Distribute it," but the one who had performed the incantation said, "Let us first go to the service of the Prophet (peace and blessings of Allah be upon him) and mention this to him. After that, we will see what command he gives." So all of them went to the service of the Messenger of Allah (peace and blessings of Allah be upon him) and mentioned it to him. The Prophet (peace and blessings of Allah be upon him) said, "How did you know that Surah Al-Fatiha is also a ruqyah (incantation)?" After that, the Prophet (peace and blessings of Allah be upon him) said, "You did the right thing. Distribute it and allocate a share for me as well." Upon saying this, the Messenger of Allah (peace and blessings of Allah be upon him) smiled.

Hazrat Jabir bin Abdullah (may Allah be pleased with him) narrated that I heard the Noble Prophet (peace and blessings be upon him) say: If there is any good in your remedies, or he said: If there is good in these remedies of yours, then it is in cupping, drinking honey, and cauterization with fire, if it suits the illness. But I do not like cauterization with fire.

Hazrat Ibn Abbas (may Allah be pleased with them both) narrated that the Prophet Muhammad (peace and blessings be upon him) had cupping done and also paid the one who performed the cupping. (If cupping were unlawful, then he would neither have it done nor pay for it.)

Hazrat Anas (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) had cupping done, and he (peace be upon him) never wronged anyone regarding wages for work.

Hazrat Abdullah bin Umar (may Allah be pleased with them) narrated that the Prophet Muhammad (peace and blessings be upon him) said: Fever is due to the effect of the heat of Hell. Therefore, cool it with water.

When a woman suffering from fever was brought to Hazrat Asma bint Abi Bakr Siddiq (may Allah be pleased with her), she would supplicate for her and pour water into her collar. She used to say that the Messenger of Allah (peace and blessings be upon him) commanded us to cool fever with water.
