Aamir bin Sa’d narrates from his father (Sayyiduna Sa’d bin Abi Waqqas, may Allah be pleased with him) regarding the Prophet Muhammad (peace and blessings be upon him): The Prophet (peace be upon him) used to turn to the right when saying salam, until the whiteness of his blessed cheek would become visible, and he used to turn to the left when saying salam, until the whiteness of his blessed cheek would become visible. The chain of this narration is authentic.
