Silsilah as-Sahihah 552 — Prompting the Imam during congregation

Ibn Abzi narrates from his father Abzi (may Allah be pleased with him) that (one day) the Noble Prophet (peace and blessings be upon him) overlooked a verse, and after completing the prayer, he asked: "Is Ubayy among the people?" Sayyiduna Ubayy (may Allah be pleased with him) asked: "Has such-and-such verse been abrogated or have you forgotten it?" The Prophet (peace and blessings be upon him) said: "Rather, it was made me forget."
