[Machine] The Messenger of Allah ﷺ used to greet with his right hand and his left hand, until his cheek was visible saying, "Peace be upon you and the mercy of Allah." This is reported by Sa'd bin Abi Waqqas and Jabir bin Samurah from the Prophet ﷺ.
كَانَ رَسُولُ اللهِ ﷺ يُسَلِّمُ عَنْ يَمِينِهِ وَعَنْ شِمَالِهِ حَتَّى يَبْدُوَ خَدُّهُ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ وَهُوَ ثَابِتٌ عَنْ سَعْدِ بْنِ أَبِي وَقَّاصٍ وَجَابِرِ بْنِ سَمُرَةَ عَنِ النَّبِيِّ ﷺ
