It was narrated from ‘Abdur Rahman bin Al-Aswad from his father — and ‘Alqamah — that ‘Abdullah said: “I saw the Messenger of Allah صلی اللہ علیہ وآلہ وسلم say the Takbir every time he went down and got up, or stood or sat; he said the Salam on his right and his left: ‘As-salamu ‘alaykum wa ra (Peace be upon you and the mercy of Allah),’ until the whiteness of his cheek could be seen.” He said: “And I saw Abu Bakr and ‘Umar, may Allah be pleased with them both, doing the same.” (Sahih)
