On the authority of ʿAbdullāh ibn ʿAmr, who said: The Messenger of Allāh, peace and blessings be upon him, said: "Whoever kills a person from the people of the dhimmah will not find the fragrance of Paradise, and indeed its fragrance is found from a distance of forty years' journey."(1)

‌‌14 - Chapter: The Dropping of Retaliation Between Slaves for Offenses Less Than Murder

4751 - Isḥāq ibn Ibrāhīm informed us, saying: Muʿādh ibn Hishām informed us, saying: My father narrated to me, from Qatādah, from Abū Naḍrah, from ʿImrān ibn Ḥuṣayn, that a young slave belonging to poor people cut off the ear of a young slave belonging to rich people. They came to the Prophet, peace and blessings be upon him, and he did not award them anything.(2)

(1) Its chain of transmission is authentic. Mujāhid: he is Ibn Jabr. It is in "Al-Sunan al-Kubrā" under numbers (6926) and (8689).
Aḥmad (6745) also narrated it from Ismāʿīl ibn Muḥammad al-Muʿaqqib, from Marwān al-Fazārī, with this chain of transmission.
Al-Bukhārī (3166) and (6914) narrated it via ʿAbd al-Wāḥid ibn Ziyād, and Ibn Mājah (2686) via Abū Muʿāwiyah al-Ḍarīr, both from al-Ḥasan ibn ʿAmr al-Fuqaymī, from Mujāhid, from ʿAbdullāh ibn ʿAmr, with it, but they did not mention Junādah ibn Abī Umayyah in it. Al-Ḥāfiẓ said in "Al-Fatḥ" 6/270: Al-Dāraquṭnī favored this addition — meaning the addition of Junādah in the chain — but Mujāhid's hearing from ʿAbdullāh ibn ʿAmr is established, and he was not a mudallis, so it is possible that Mujāhid heard it first from Junādah, then met ʿAbdullāh ibn ʿAmr, or they both heard it together, and Junādah confirmed it for him, so he narrated it from ʿAbdullāh ibn ʿAmr sometimes, and from Junādah other times.

(2) Its chain of transmission is authentic. Muʿādh ibn Hishām: he is Ibn ʿAbdullāh al-Dastawāʾī, and Qatādah: he is Ibn Diʿāmah, and Abū Naḍrah: he is al-Mundhir ibn Mālik ibn Quṭʿah al-ʿAbdī. It is in "Al-Sunan al-Kubrā" under number (6927).
Aḥmad (19931) also narrated it — and from him Abū Dāwūd (4590) — from Muʿādh ibn Hishām, with this chain of transmission.
Al-Sindī said: Regarding his statement "that a young slave" — al-Khaṭṭābī said: This offending young man was free. I say: He meant that "ghulām" here means a young boy, not a slave, as the author understood it. Then he — meaning al-Khaṭṭābī — said: And his offense was accidental, and his ʿāqilah (kinsmen responsible for blood money) were poor, and the ʿāqilah only contribute from those among them who have means and wealth, and nothing is due from the poor among them. As for the slave, if he commits an offense, then his offense is against his own person (i.e., he is surrendered for it).
