Narrates Ibn Sirin:

Abu Huraira said, "Allah's Apostle led us in one of the two 'Isha' prayers (Abu Huraira named that prayer but I forgot it)." Abu Huraira added, "He prayed two Rakat and then finished the prayer with Tasleem. He stood up near a piece of wood Lying across the mosque and leaned on it in such a way as if he was angry. Then he put his right hand over the left and clasped his hands by interlacing his fingers and then put his J right cheek on the back of his left hand. The people who were in haste left the mosque through its gates. They wondered whether the prayer was reduced. And amongst them were Abu Bakr and 'Umar but they hesitated to ask the Prophet. A long-handed man called Dhul-Yadain asked the Prophet, 'O Allah's Apostle! Have you;
forgotten or has the prayer been reduced?' The Prophet replied, 'I have neither forgotten nor has the prayer been reduced' The Prophet added, 'Is what Dhul Yadain has said true?' They (the people) said, 'Yes, it is true.' The Prophet stood up again and led the prayer, completing the remaining prayer, forgotten by him, and performed Tasleem, and then said, 'Allahu Akbar.' And then he did a prostration as he used to prostrate or longer than that. He then raised his head saying, 'Allahu Akbar; he then again said, 'Allahu Akbar', and prostrated as he used to prostrate or longer than that. Then he raised his head and said, 'Allahu Akbar.' " (The subnarrator added, "I think that they asked (Ibn Sirin) whether the Prophet completed the prayer with Taslim. He replied, "I heard that 'Imran bin Husain had said, 'Then he (the Prophet) did Taslim.")
