“The Messenger of Allah ﷺ used to say the Salam to his right and to his left, until the whiteness of his cheek could be seen (saying): ‘As-salamu ‘alaikum wa rahmatullah, as-salamu ‘alaikum wa rahmatullah.’” (Using translation from Ibn Mājah 916)
كَانَ رَسُولُ اللهِ ﷺ يُسَلِّمُ عَنْ يَمِينِهِ حَتَّى يَبْدُوَ بَيَاضُ خَدِّهِ يَقُولُ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ وَعَنْ يَسَارِهِ حَتَّى يَبْدُوَ بَيَاضُ خَدِّهِ يَقُولُ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ
