Actions while Praying

Bukhari :: Book 2 :: Volume 22 :: Hadith 322

Narrated 'Abdullah bin Buhaina Al-Asdi:

(the ally of Bani 'Abdul Muttalib) Allah's Apostle stood up for the Zuhr prayer and he should have sat (after the second Raka but he stood up for the third Raka without sitting for Tashah-hud) and when he finished the prayer he performed two prostrations and said Takbir on each prostration while sitting, before ending (the prayer) with Taslim; and the people too performed the two prostrations with him instead of the sitting he forgot.
