Majma al-Zawaid 15717 — Reports on the virtue of Ubayy bin Ka'b

Sayyiduna Abu Habbah al-Badri (may Allah be pleased with him) said: When the surah "Those who disbelieved among the People of the Book were not" was revealed to its end, Sayyiduna Jibril (peace be upon him) said: "O Messenger of Allah! Your Lord commands you to recite it to Ubayy." The Prophet (peace and blessings be upon him) said to Sayyiduna Ubayy (may Allah be pleased with him): "Jibril has instructed me to recite this surah to you." Sayyiduna Ubayy (may Allah be pleased with him) asked: "O Messenger of Allah! Was I mentioned there?" The Prophet (peace and blessings be upon him) replied: "Yes!" Then Sayyiduna Ubayy (may Allah be pleased with him) began to weep.
Ahmad and al-Tabarani recorded it; its chain contains Ali bin Zayd, who is hasan al-hadith (good in hadith), and the rest of its narrators are the narrators of the Sahih.
