Several transmitters have related this report from him.
Hariz (1) ibn ʿUthmān narrated from ʿAbd al-Raḥmān ibn Abī ʿAwf al-Jurashī, from Muʿāwiyah, who said:
“I saw the Messenger of Allah ﷺ sucking his—meaning al-Ḥasan’s—tongue or lip, and a tongue or pair of lips that the Messenger of Allah ﷺ has sucked will never be subjected to punishment.”
Aḥmad recorded it (2).
Yaḥyā ibn Maʿīn said: Yaḥyā ibn Saʿīd al-Umawī narrated to us, from al-Aʿmash, from Abū Sufyān, from Jābir:
that the Prophet ﷺ said about al-Ḥasan, “This son of mine is indeed a leader; through him Allah will reconcile two groups of Muslims (3).”
A similar wording is reported in the narration of al-Ḥasan from Abū Bakrah (4).
This ḥadith was transmitted by Yūnus, Manṣūr ibn Zādhān, Isrāʾīl Abū Mūsā, Hishām ibn Ḥassān, Ashʿath ibn Sawwār, Mubārak ibn Faḍālah, and others, from him.
Al-Wāqidī reported: Mūsā ibn Muḥammad al-Taymī related to me, from his father, that when ʿUmar established the dīwān (state register), he placed al-Ḥasan and al-Ḥusayn on the same stipend as their father because of their closeness to the Messenger of Allah ﷺ, allotting each of them five thousand dirhams.
= Ibn Hibban declared the hadith sound (no. 2238). Al-Haythami cites it in his Majmaʿ, 9/177, attributing it to Ahmad and al-Tabarani, and comments: “All of its transmitters are those of the Sahih except ʿUmayr b. Ishaq, and he is reliable.” Al-Hakim also graded it sahih (3/168) and al-Dhahabi concurred, although in his chain the name “Muhammad” appears in place of ʿUmayr b. Ishaq. The likely explanation is the accidental omission of the word “Abi,” for ʿUmayr b. Ishaq’s kunya is Abu Muhammad. It is improbable that this “Muhammad” refers to Ibn Sirin, since the hadith is only known through ʿUmayr b. Ishaq.
(1) In the printed edition the name was misread as “Jarir”; the same error occurs in the Musnad and in al-Bidaya, 8/36.
(2) 4/93; the chain of transmission is authentic.
(3) The isnad is strong. Al-Haythami reproduces it in Majmaʿ, 9/178, stating that al-Tabarani transmitted it in both al-Awsat and al-Kabir, and al-Bazzar also recorded it. The chain contains ʿAbd al-Rahman b. Mughrā; several scholars deemed him trustworthy, though there is some weakness in him, while the remaining narrators in al-Bazzar’s version are transmitters of the Sahih.
