This is a ḥasan (good) ḥadīth, but it is gharīb (singular in transmission), and its chain of narration is not continuous. Abū Jaʿfar Muḥammad ibn ʿAlī ibn al-Ḥusayn did not meet ʿAlī ibn Abī Ṭālib.

Chapter 19

1598 – Al-Ḥasan ibn ʿAlī al-Khallāl narrated to us, saying: Azhar ibn Saʿd al-Sammān narrated to us, from Ibn ʿAwn, from Muḥammad ibn Sīrīn, from ʿAbd al-Raḥmān ibn Abī Bakrah, from his father:

That the Prophet, peace and blessings be upon him, delivered a sermon, then came down and called for two rams.

= in need, in the mosque or in the Ṣuffah, and she did that. She said: When I gave birth to Ḥusayn, I did the same. In it is ʿAbd Allāh ibn Muḥammad ibn ʿAqīl, who is weak but may be considered as supporting evidence, and ʿAlī ibn al-Ḥusayn did not meet Abū Rāfiʿ, the freed slave of the Messenger of Allah, peace and blessings be upon him. See the rest of its takhrīj in "al-Musnad."

Al-Bazzār (1238 – Kashf al-Astār), al-Ṭabarānī in "al-Kabīr" (2575) and in "al-Awsaṭ" (127), and al-Bayhaqī 9/299 also narrated via ʿAbd Allāh ibn Lahīʿah, from ʿUmārah ibn Ghaziyyah, from Rabīʿah ibn Abī ʿAbd al-Raḥmān, from Anas ibn Mālik: that the Messenger of Allah, peace and blessings be upon him, ordered that the heads of al-Ḥasan and al-Ḥusayn, the sons of ʿAlī ibn Abī Ṭālib, be shaved on their seventh day, then he gave in charity silver equal to their weight. In it is ʿAbd Allāh ibn Lahīʿah, who had a poor memory.

As for the fact that he, peace and blessings be upon him, performed the ʿaqīqah for al-Ḥasan ibn ʿAlī, this has come in authentic aḥādīth, including the ḥadīth of Buraydah ibn al-Ḥuṣayb in Aḥmad, number (23001), and we have mentioned the rest of its supporting witnesses in the commentary on it, and on the ḥadīth of Abū Rāfiʿ, the freed slave of the Messenger of Allah, peace and blessings be upon him, number (27183). Refer to them there.

We say: Thus the ḥadīth, with all its paths and supporting witnesses, is ḥasan, Allah willing.
