Abdullah said: "I saw the Messenger of Allah ﷺ say the Takbir every time he went down and got up, or stood or sat; he said the Salam on his right and his left: 'As-salamu alaykum wa rahmatulah (peace be upon you and the mercy of Allah ),' until the whiteness of his cheek could be seen." He said: "And I saw Abu Bakr and 'Umar, may Allah (SWT) be pleased with them both, doing the same." (Using translation from Nasāʾī 1142)
رَأَيْتُ النَّبِيَّ ﷺ يُكَبِّرُ فِي كُلِّ رَفْعٍ وَوَضْعٍ وَقِيَامٍ وَقُعُودٍ وَيُسَلِّمُ عَنْ يَمِينِهِ وَعَنْ شِمَالِهِ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ حَتَّى أَرَى بَيَاضَخَدِّهِ وَرَأَيْتُ أَبَا بَكْرٍ وَعُمَرَ يَفْعَلَانِ ذَاكَ
