He then stood near a piece of wood in front of the mosque and put his hand on it. Abu Bakr and ‘Umar were amongst those who were present, but they dared not talk to him about it (because of being awed by him), and those who were in a hurry went out. They said: "Has the prayer been reduced?" A man who was called Dhu al-Yadayn by the Prophet (may Allah's peace and blessings be upon him) said (to the Prophet): "Has the prayer been reduced or have you forgotten?" He said: "Neither have I forgotten, nor has the prayer been reduced." He said: "Certainly you have forgotten." So the Prophet offered two more Rak‘ahs and ended the prayer with Taslīm. Then he said Takbīr and performed a prostration like his ordinary prostration or a bit longer. Then he raised his head and said Takbīr. Then he put his head down and performed a prostration like his ordinary prostration or a bit longer. Then he raised his head and said Takbīr.' [Al-Bukhāri]
