Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) led the prayer and (during the recitation) left out a verse, and among the people was Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) as well. (After the prayer) he said, "O Messenger of Allah (peace and blessings be upon him), did you forget such-and-such verse or has it been abrogated?" The Prophet (peace and blessings be upon him) said: "I forgot it." This is the narration of Bundar, and in the narration of Abu Musa it is mentioned that the Noble Prophet (peace and blessings be upon him), while reciting during the prayer, forgot a verse of the Qur'an, and among the worshippers was Sayyiduna Ubayy (may Allah be pleased with him) as well. He said, "O Messenger of Allah, you forgot such-and-such verse or has it been made to be forgotten (abrogated)?" The Prophet (peace and blessings be upon him) said: "No (it has not been abrogated), rather I forgot it."

Sayyiduna Miswar bin Yazid Al-Asidi (may Allah be pleased with him) narrates that I heard the Messenger of Allah (peace and blessings be upon him) reciting in prayer, and he left out some verses. So a man said to him, "O Messenger of Allah, you left out these verses." The Prophet (peace and blessings be upon him) said: "Why did you not remind me?" In the narration of Muhammad bin Yahya, there is this addition: that the companion replied, "I thought those verses had been abrogated, that is why I did not remind you."
