Narrated Amr bin Suhaib: On his father's authority, said that his grandfather reported the Messenger of Allah ﷺ said: The blood-wit for a man who makes a covenant is half of the blood-wit for a free man.

Narrated Safwan bin Yala: On this father's authority, said: A servant of mine fought with a man and bit his hand and he drew away his hand. (One of) his front teeth fell out. So he came to the Prophet ﷺ who imposed no retaliation for his tooth, saying: Do you intend that he leaves his hand in your mouth so that you crunch it like a male camel ? He said: Ibn Abi Mulaikah told me on the authority of his grandfather that Abu Bakr (ra) imposed no retaliation on him for it, saying: May his tooth go away!

The tradition mentioned above has also been transmitted by Yala bin Umayyah through a different chain of narrators. This version has: 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.

Narrated Amr bin Suhaib: On his father's authority, said that his grandfather reported the Messenger of Allah ﷺ said: Anyone who practises medicine when he is not known as a practitioner will be held responsible.

Narrated Abdul Aziz ibn Umar ibn Abdul Aziz: Some people of the deputation which came to my father reported the Messenger of Allah ﷺ as saying: Any physician who practises medicine when he was not known as a practitioner before that and he harms (the patients) he will be held responsible.

Narrated Abdullah ibn Amr ibn al-As: The Prophet ﷺ said: Musaddad's version has: He addressed on the day of Conquest. The agreed version then goes: Beware! Every object of pride of pre-Islamic times, whether it is blood-vengeance or property, mentioned or claimed, has been put under my feet except supply of water to the pilgrims and custody of the House (the Kabah). He then said: Beware! The blood-wit for unintentional murder, such as is done with a whip and stick, is one hundred camels, forty of which are pregnant.

The tradition mentioned above has also been transmitted by Khalid with a different chain of narrators to the same effect.

Narrated Imran ibn Husayn: A servant of some poor people cut off the ear of the servant of some rich people. His people came to the Prophet ﷺ and said: Messenger of Allah! we are poor people. So he imposed no compensation on them.

Narrated Abdullah ibn Abbas: The Prophet ﷺ said: If anyone is killed blindly or, when people are throwing stones, by a stone or a whip, his blood-wit is the blood-wit for an accidental murder.

Narrated Abu Hurairah: The Prophet ﷺ said: No recompense is to be demanded if one is kicked by an animal. Abu Dawud said: An animal kicks someone with its leg while one is riding on it.
