On the authority of his grandfather, from the Prophet ﷺ, who said: "A believer shall not be killed in retaliation for a disbeliever, and whoever intentionally kills a believer shall be handed over to the heirs of the slain: if they wish, they may kill him, and if they wish, they may accept the blood money."(1)

(1) Ṣaḥīḥ bi-ghayrihi (sound due to corroborating evidence), and this chain is ḥasan (good). Sulaymān ibn Mūsā: he is al-Dimashqī, and Muḥammad ibn Rāshid: he is al-Makḥūlī, and Muslim: he is ibn Ibrāhīm al-Farāhīdī.
Its first part was narrated by Ibn Mājah (2659) via the route of ʿAbd al-Raḥmān ibn ʿAyyāsh, and by al-Tirmidhī (1471) via the route of Usāmah ibn Zayd, both from ʿAmr ibn Shuʿayb, with this chain.
It has already preceded with the author within hadith (2751). And it is in the Musnad of Aḥmad (7012).
Its second part was narrated by Ibn Mājah (2626) and al-Tirmidhī (1444) via the route of Muḥammad ibn Rāshid, with this chain.
And it is in the Musnad of Aḥmad (7033).
Its first part has a supporting witness from the hadith of ʿAlī ibn Abī Ṭālib in al-Bukhārī (111) and Muslim (1370), and it will come with the author within hadith (4530).
Its second part has a supporting witness from the hadith of Abū Hurayrah and Abū Shurayḥ al-Khuzāʿī that preceded with the author. And their chains are ṣaḥīḥ (sound).
Note: This hadith we have established from the margin of (H), and it indicated that it is in the narration of Ibn al-Aʿrābī. Al-Mizzī mentioned it in al-Tuḥfah (8708) and attributed it to the narration of Ibn Dāsah and Ibn al-Aʿrābī.
