Sunan Abi Dawud — Medicine (Kitab Al-Tibb)

In the pre-Islamic period we used to apply spells and we asked: Messenger of Allah ! how do you look upon it ? He replied : Submit your spells to me. There is no harm in spells so long as they involve no polytheism.

The Prophet (ﷺ) smelt the breath of Ma’iz.

The Prophet (ﷺ) said to the man bit him: If you wish that you give him control over your hand and he bites it, and then you drive it away from his mouth (you may do it). He imposed no retaliation for his teeth.

“Indeed, after me you will see preferential treatment, and matters that you dislike.” They said: “Then what do you command us” He said: “Give them their rights, and ask Allah for yours.”

“Do not leave fire in your houses when you go to sleep.”

“We, the family of Muhammad (ﷺ), would stay for a month during which no fire would be lit (for cooking) and we had only dates and water.”
