Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) ended the prayer after two rak‘ahs. Then a man from the allies of Banu Zuhrah, Dhu’l-Yadayn from Khuza‘ah, said to him, “O Messenger of Allah (peace and blessings be upon him), has the prayer been shortened or did you forget?” The Prophet (peace and blessings be upon him) said, “Neither of these has happened.” Then the Messenger of Allah (peace and blessings be upon him) turned to the people and asked, “Is Dhu’l-Yadayn speaking the truth?” They replied, “Yes.” So the Prophet (peace and blessings be upon him) completed the remainder of his prayer and did not perform the two prostrations of forgetfulness until the people convinced him (that he had indeed forgotten).
