when Ibn Abī Ṭālib was killed, al-Ḥasan stood up to deliver a sermon ... and he mentioned it. It was recorded by al-Bazzār (2573): ʿAmr ibn ʿAlī narrated to us, Abū ʿĀṣim narrated to us, Sukkīn ibn ʿAbd al-ʿAzīz narrated it. It was also recorded by Abū Yaʿlá (4/1596): Ibrāhīm ibn al-Ḥajjāj narrated to us: Sukkīn narrated it, except he added to the isnād, saying: from Khālid ibn Jābir, from his father, from al-Ḥasan ... and he added Jābir, the father of Khālid. Similarly, it was narrated by al-Ṭabarānī in "al-Muʿjam al-Awsaṭ" (2/235/8634) through ʿAbd al-Raḥmān, who said: Sukkīn ibn ʿAbd al-ʿAzīz narrated it. Al-Ṭabarānī said: "No one narrated it except Sukkīn, and ʿAbd al-Raḥmān was unique in narrating it." I said: Rather, he was followed by Ibrāhīm ibn al-Ḥajjāj as mentioned earlier. Al-Bazzār said: "We do not know anyone who narrated it [from] Ḥafṣ except Sukkīn, and its isnād is sound." So he said! Ḥafṣ ibn Khālid ibn Jābir, his father, and his grandfather are unknown, and Ḥafṣ and his father were mentioned by Ibn Abī Ḥātim (1/2/172, 323) without any criticism or commendation. He said about Ḥafṣ: "He narrated from his father. Sukkīn ibn ʿAbd al-ʿAzīz narrated from him." He said about Khālid ibn Jābir: "He narrated from al-Ḥasan ibn ʿAlī, and his son Ḥafṣ ibn Khālid ibn Jābir narrated from him." I said: And this matches the narration of al-Bazzār. But in "Tārīkh al-Bukhārī" (1/2/362-363): "Ḥafṣ ibn Khālid ibn Jābir, he heard from his father about his grandfather: al-Ḥasan ibn ʿAlī said: ʿAlī was killed
