It was narrated that ‘Abdullah said: “I saw the Messenger of Allah صلی اللہ علیہ وآلہ وسلم saying the Takbir every time he
went down or came up, or stood or sat, and he said the Salam to his right and to his left: As-salamu ‘alaykum wa rahrnatullah, as-salamu ‘alaykum wa ra (Peace be upon you and the mercy of Allah, peace be upon you and the mercy of Allah), until the whiteness of his cheek could be seen. And I saw Abu Bakr and ‘Umar, may Allah be pleased with them, doing likewise.” (Sahih)
