Imam Maalik مالك بن أنس بن مالك بن أبي عامر · Chapters on Medicine

"Cheer up, for indeed Allah said: 'It is My Fire which I impose upon My sinning slave as his portion of the Fire." (Hasan) Al-Hasan said: "They would hope that the fever that occurred at night would atone for any deficiency caused by sins."

It was narrated from Anas that the Prophet (ﷺ) allowed Ruqyah for the scorpion’s sting, the evil eye, and Namlah (sores or small pustules ulcers or sores on a person’s sides).

“The Prophet (ﷺ) enjoined killing Dhit-Tufytain* for it takes away the sight and causes miscarriage.” *That means a wicked snake.
