Sahih al-Bukhari
Forgetfulness in Prayer
Chapter: To say Takbir in the prostrations of Sahw
Narrated `Abdullah bin Buhaina Al-Asdi:
(the ally of Bani `Abdul Muttalib) Allah's Messenger (ﷺ) stood up for the Zuhr prayer and he should have sat (after the second rak`a but he stood up for the third rak`a 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.
