[Machine] The Prophet ﷺ used to say: "I saw the Messenger of Allah ﷺ raising his right hand in greeting until the whiteness of his cheek could be seen, and raising his left hand until the whiteness of his cheek could be seen."
كَانَ رَسُولُ اللهِ ﷺ وَقَالَ أَبُو سَعِيدٍ رَأَيْتُ رَسُولَ اللهِ ﷺ يُسَلِّمُ عَنْ يَمِينِهِ حَتَّى يُرَى بَيَاضُ خَدِّهِ وَعَنْ يَسَارِهِ حَتَّى يُرَى بَيَاضُ خَدِّهِ
