Among the Successors are ʿAmr and Arqam, the sons of Shuraḥbīl.
Among those who number three are ʿAlī, Jaʿfar, and ʿAqīl, the sons of Abū Ṭālib; and Sahl, ʿAbbād, and ʿUthmān, the sons of Ḥanīf.
Outside the circle of Companions we find ʿAmr, ʿUmar, and Shuʿayb, the sons of Shuʿayb.
Among groups of four are Suhayl, ʿAbd Allāh, Muḥammad, and Ṣāliḥ, the sons of Abū Ṣāliḥ.
Among groups of five are Sufyān, Ādam, ʿImrān, and Muḥammad, the sons of ʿUyaynah—all of them transmitted hadith.
Among groups of six are Muḥammad, Anas, Yaḥyā, Maʿbad, Ḥafṣah, and Karīmah, the children of Sirīn, although some replace Karīmah with Khālid.
Muḥammad narrated from Yaḥyā, who narrated from Anas, who narrated from Anas ibn Mālik a hadith; this is a curious rarity—three brothers, each transmitting from the other.
Among groups of seven are al-Nuʿmān, Maʿqil, ʿAqīl, Suwayd, Sinān, ʿAbd al-Raḥmān, and a seventh whose name has not reached us, the sons of Muqarrin. They were Emigrant Companions unmatched by anyone else, and it is said that they witnessed the Battle of the Trench. Allah knows best.

Fathers narrating from their sons

Al-Khaṭīb composed a monograph on this subject. In it he cites, for example, the report of al-ʿAbbās from his son al-Faḍl that the Messenger of Allah (peace and blessings be upon him) combined the two prayers at Muzdalifah; the report of Wāʾil ibn Dāwūd from his son Bakr, who narrates from al-Zuhrī; and the account of Muʿtamir ibn Sulaymān, who said, “My father told me, ‘You once narrated to me—from me—through Ayyūb, from al-Ḥasan, that the word wayḥ is an expression of mercy.’” This charming anecdote gathers together several categories that I have explained in the larger work. Allah knows best.
