Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates: I remember very well about the Noble Prophet (peace and blessings be upon him) that he used to say takbeer every time he stood up, bowed, stood, and sat, and when turning to the right and to the left for salam, he used to say, "As-salamu 'alaykum wa rahmatullah, as-salamu 'alaykum wa rahmatullah," until the whiteness of his blessed cheek would become visible. (Sayyiduna Abdullah says) I have also seen Sayyiduna Abu Bakr and Sayyiduna Umar (may Allah be pleased with them both) doing the same.
