Muslim transmitted it through ʿAbd al-Ḥamīd.
It is also found with another chain: al-Zubaydī, from al-Zuhrī, from Isḥāq, the client of al-Mughīra, from Ubayy. (1)
Abū Ṣāliḥ al-Kātib related: Mūsā ibn ʿUlayy narrated to us from his father that ʿUmar delivered a sermon at al-Jābiya, saying:
“Whoever wishes to ask about the Qur’an, let him come to Ubayy ibn Kaʿb; whoever wishes to ask about the prescribed shares of inheritance, let him go to Zayd; whoever wishes to ask about jurisprudence, let him go to Muʿādh; and whoever wishes to ask about matters of wealth, let him come to me, for Allah has made me its guardian and distributor.” (2)
Al-Wāqidī reported the same narration from Mūsā as well.
Abū Bakr ibn ʿAyyāsh—through ʿĀṣim, from Zir—said:
“I came to Madinah and visited Ubayy. I said, ‘May Allah have mercy on you; show me kindness’—for he was a man with a streak of sternness. I then asked him about the Night of Decree, and he replied, ‘It is the twenty-seventh night.’” (3)
Sufyān al-Thawrī—through Aslam al-Minqarī, from ʿAbd Allah ibn ʿAbd al-Raḥmān ibn Abzā, from his father—reported that Ubayy ibn Kaʿb said:
“The Messenger of Allah ﷺ told me, ‘I have been commanded to recite the Qur’an to you.’ I asked, ‘O Messenger of Allah, was I mentioned to you by name?’ He replied, ‘Yes.’”
I asked Ubayy, “Did that delight you?”
He answered, “Why should it not, when He—Exalted is He—says: ‘Say: In the bounty of Allah and in His mercy, in that let them rejoice.’ [Yūnus 58]” (4)
