On the authority of ʿUmar ibn al-Khaṭṭāb, who said: I heard the Messenger of Allah ﷺ say: "A father is not subjected to retaliation for [killing] his son." (1)

1459 - Muḥammad ibn Bashshār narrated to us, saying: Ibn Abī ʿAdī narrated to us, on the authority of Ismāʿīl ibn Muslim, on the authority of ʿAmr ibn Dīnār, on the authority of Ṭāwūs, on the authority of Ibn ʿAbbās, on the authority of the Prophet ﷺ, who said: "Legal punishments are not carried out in mosques, and a father is not killed for [killing] his son." (2)

This is a ḥadīth that we do not know, with this chain of transmission, as raised [to the Prophet] except through the narration of Ismāʿīl ibn Muslim. And concerning Ismāʿīl ibn Muslim al-Makkī, some scholars have spoken critically regarding his memory.

--------------------------------------------
(1) A ḥasan ḥadīth; Ḥajjāj ibn Arṭāh was followed [by other narrators].
It was also recorded by Ibn Mājah (2662) via the chain of Ḥajjāj ibn Arṭāh, with this chain of transmission, and it is in al-Musnad (98).
It was also recorded by Ibn al-Jārūd (788), al-Dāraquṭnī 3/140-141, and al-Bayhaqī 8/38 via the chain of Muḥammad ibn ʿAjlān, on the authority of ʿAmr ibn Shuʿayb, with it. Al-Bayhaqī said in Maʿrifat al-Sunan wa al-Āthār (15790): This chain of transmission is ṣaḥīḥ!

(2) A ḥasan ḥadīth.
It was also recorded by Ibn Mājah (2599) and (2661) via the chain of Ismāʿīl ibn Muslim, with it.
It was also recorded by al-Dāraquṭnī 3/142 and al-Bayhaqī 8/39 via the chain of Abū Ḥafṣ ʿUmar ibn ʿĀmir al-Saʿdī, on the authority of ʿUbayd Allāh ibn al-Ḥasan al-ʿAnbarī, and by al-Dāraquṭnī 3/142 via the chain of Saʿīd ibn Bashīr, on the authority of Qatādah — both of them (ʿUbayd Allāh and Qatādah) on the authority of ʿAmr ibn Dīnār, with it. Although these chains are not free of weakness, the ḥadīth is strengthened to the level of ḥasan by them, and by its supporting witness cited above from ʿUmar ibn al-Khaṭṭāb.
