Bukhari

Narrated Abu Huraira.: Once Allah's Apostle offered two rak`at and finished his prayer. So Dhul-Yadain asked him, "Has the prayer been reduced or have you forgotten?" Allah's Apostle said, "Has Dhul-Yadain spoken the truth?" The people replied in the affirmative. Then Allah's Apostle stood up and offered the remaining two rak`at and performed Taslim, and then said Takbir and performed two prostrations like his usual prostrations, or a bit longer, and then got up.

And Anas (may Allah be pleased with him) and Hasan al-Basri (may Allah have mercy on him) gave salam (i.e., after the prostration of forgetfulness) and did not recite the tashahhud, and Qatadah said that he should not recite the tashahhud.

Narrated Abu Huraira: The Prophet offered one of the evening prayers (the sub-narrator Muhammad said, "I think that it was most probably the `Asr prayer") and he finished it after offering two rak`at only. He then stood near a price of wood in front of the Mosque and put his hand over it. Abu Bakr and `Umar were amongst those who were present, but they dared not talk to him about that (because of excessive respect for him), and those who were in a hurry went out. They said, "Has the prayer been reduced?" A man who was called Dhul-Yadain by the Prophet 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`at and performed Taslim and then said Takbir and performed a prostration of Sahu like his ordinary prostration or a bit longer and then raised his head and said Takbir and then put his head down and performed a prostration like his ordinary prostration or a bit longer, and then raised his head and said Takbir.

Narrated Salama bin 'Alqama: I asked Muhammad (bin Seereen) whether Tashah-hud should be recited after the two prostrations of Sahu. He replied, "It is not (mentioned) in Abu Huraira's narration . "
