Hadith 330

Narrated 'Abdullah bin Buhainah (RA): The Prophet (SAW) led them in the Zuhr prayer, and when he stood up at the end of the first two Rak'at and did not sit, the people stood up with him. When he finished the Salat (prayer) and the people expected him to do the Taslim (salutation), he uttered the Takbir while sitting and made two prostrations before saying the Taslim (salutation), then he uttered the Taslim (salutation). [Reported by as-Sab'ah and this is al-Bukhari's wording].
