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."
