It is narrated from Sayyiduna ‘Ubada bin Samit (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When a person is wounded in his body and he forgives (the one who wounded him), then Allah Almighty erases his sins in proportion to his forgiveness.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that whenever a case involving retribution (qisas) was presented to the Noble Prophet (peace and blessings be upon him), he (peace and blessings be upon him) would first command forgiveness.

Narrated from Sayyiduna Anas (may Allah be pleased with him) that his paternal aunt, Rubayyi' bint Nadr, broke the tooth of a slave girl. When she offered blood money to the heirs of that slave girl, they refused to accept it. She requested forgiveness, but they were not willing to forgive either. So the Noble Prophet (peace and blessings be upon him) ordered that retribution (qisas) be carried out. The brother of Sayyiduna Anas’s aunt and his uncle, Sayyiduna Anas bin Nadr (may Allah be pleased with him), came and said: O Messenger of Allah (peace and blessings be upon him)! Will my sister Rubayyi’s tooth be broken? No, by the One Who has sent you with the truth! Her tooth will not be broken. The Messenger of Allah (peace and blessings be upon him) said: O Anas bin Nadr! The Book of Allah demands retribution (qisas). Meanwhile, the aggrieved people forgave her. At that time, the Messenger of Allah (peace and blessings be upon him) said: There are some servants of Allah that if they swear an oath by Allah, He fulfills it for them.

(Second chain) It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the sister of Rabi', Umm Haritha, wounded a person. They brought the dispute to the Messenger of Allah (peace and blessings be upon him). The Messenger of Allah (peace and blessings be upon him) said: Qisas (retaliation) will be taken, qisas. But Umm Rabi' said: O Messenger of Allah! Will qisas be taken from such-and-such woman? No, by Allah! Qisas will never be taken from her. The Noble Prophet (peace and blessings be upon him) said: Subhan Allah! O Umm Rabi'! It is a matter of Allah Almighty's Book. But Umm Rabi' again said: No, I am saying by Allah that qisas will not be taken from her. She kept saying this until those people agreed to accept blood money. The Messenger of Allah (peace and blessings be upon him) said: There are some servants of Allah Almighty that if they swear an oath by Allah, He fulfills their oath.

It is narrated from a man named Majda of Banu Sahm, he says: I had a dispute with a slave in Makkah, now he bit my ear and a part of it was cut off, or I had bitten his ear. When Sayyiduna Abu Bakr (may Allah be pleased with him) came to us for Hajj, our case was presented in his court. He said: Take them to Umar ibn Khattab (may Allah be pleased with him), if the wound is deserving of retaliation, then he will have retaliation carried out. When we were brought to Sayyiduna Umar (may Allah be pleased with him), he saw and said: Yes, this wound has reached the limit for retaliation, call a barber. When they mentioned the barber, he said: I heard the Messenger of Allah (peace and blessings be upon him) say: I gave my maternal aunt a slave and I hope that Allah Almighty will bless her in that slave, and I forbade her from making him a cupper, butcher, or goldsmith.

It is narrated from Sayyidna Ali bin Umayyah and Salamah bin Umayyah (may Allah be pleased with them), they say: We set out with the Messenger of Allah (peace and blessings be upon him) in the expedition of Tabuk. There was another companion with us. He and another Muslim got into a fight. That man bit the other's arm, so he pulled his hand out of his mouth and his front tooth fell out. That man went to the Noble Prophet (peace and blessings be upon him) and demanded blood money. The Prophet (peace and blessings be upon him) said: One of you bites his brother like a bull and then comes to demand blood money? There is no blood money for this. The Prophet (peace and blessings be upon him) declared his claim for blood money invalid.

(Second chain) It is narrated from Sayyidna Ali bin Umayyah, may Allah be pleased with him, who says: I participated with the Noble Prophet, peace and blessings be upon him, in the army of hardship, that is, the Battle of Tabuk. This battle is among those deeds of mine on which I rely the most. I had a laborer, who got into a fight with another man. One of them bit the other, and the other pulled his finger away, causing his tooth to fall out. He went to the Noble Prophet, peace and blessings be upon him, to complain, but the Prophet, peace and blessings be upon him, said: Would he have kept his hand in your mouth and you kept chewing it like a bull?

Narrated from Sayyiduna Imran bin Husain (may Allah be pleased with him) that Ya'la bin Munyah or Ibn Umayyah had a fight with a man. One of them bit the other's hand, and to save himself, he pulled his hand away, causing one or two teeth of the biter to fall out. When both of them brought their dispute to the Prophet Muhammad (peace and blessings be upon him), he said: "Does one of you bite his brother like a bull? There is no blood money for such a person." In another narration, it is stated: The Prophet (peace and blessings be upon him) invalidated his blood money and said: "Did you want to chew your brother's flesh like a bull?"

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that a man struck another with a horn and injured his foot. The injured man said: O Messenger of Allah! Have me take retribution from him. The Prophet (peace and blessings be upon him) said: Do not be hasty, wait until your wound heals. But when the man insisted on taking retribution, the Prophet (peace and blessings be upon him) allowed him to do so. However, after taking retribution, the one who took it became lame, while the one from whom retribution was taken became healthy. Now the one who took retribution came again to the Noble Prophet (peace and blessings be upon him) and said: O Messenger of Allah! I have become lame and the man concerned has recovered. The Prophet (peace and blessings be upon him) said to him: Did I not command you not to take retribution until your wound healed? But you disobeyed me, so Allah deprived you of healing and your wound was wasted. Then, after the incident of the man who became lame, the Messenger of Allah (peace and blessings be upon him) gave this ruling: Whoever is wounded should not take retribution until his wound heals; when his wound heals, then he may take retribution.

Narrated by Sayyiduna Hakim bin Hizam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "No legal punishments should be carried out in the mosques, nor should retribution (qisas) be taken there."
