“There is no retaliatory retribution for a maʾmūmah wound, a jāʾifah wound, or a munaqqilah wound.” Ibn Mājah (2/140–141) and Abū Yaʿlā (4/1580) recorded it, and al-Bayhaqī narrated it from the latter, through Rushdayn ibn Saʿd, from Muʿāwiyah ibn Ṣāliḥ, from Muʿādh ibn Muḥammad al-Anṣārī, from Ibn Aṣbahān, from him.

I say: This is a weak chain of transmission. Concerning Ibn Aṣbahān, al-Ḥāfiẓ said: “His name is, I believe, ʿUqbah. If that is so, then his narration is disconnected; otherwise, he is unknown.” I say: His certainty that it is disconnected is open to question, for they mentioned that he narrated from ʿUthmān ibn ʿAffān, who died in the year 35, whereas al-ʿAbbās died in the year 32; it was also said 33, and also said 34. And Allah knows best.

A number of trustworthy narrators reported from Muʿādh ibn Muḥammad al-Anṣārī, and Ibn Ḥibbān declared him trustworthy. Al-Ḥāfiẓ said: “Acceptable.” Rushdayn ibn Saʿd is weak. However, Ibn Lahīʿah corroborated him, reporting it from Muʿādh through the same chain. Abū Yaʿlā narrated this. I say: Thus, in my view, the hadith is good when its two chains are considered together. And Allah knows best.

Then Abū Yaʿlā (4/1581) narrated from ʿAbd Allāh ibn Wahb: Ibn Lahīʿah narrated to us from Muʿādh ibn Muḥammad al-Anṣārī, who said: ʿAmr ibn Maʿdī Karib informed me: “A man from Banū Kinānah inflicted a maʾmūmah wound upon a man, and ʿUmar ibn al-Khaṭṭāb wanted to exact retaliatory retribution from him. Al-ʿAbbās said to him: ‘I heard the Messenger of Allah, peace and blessings be upon him,’” then he mentioned it, “so he made him pay the blood money.”

There are two narrators named ʿAmr, as stated in al-Jarḥ (3/1/260), and nothing was mentioned concerning either of them.
