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."  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ يُكَبِّرُ فِي كُلِّ خَفْضٍ وَرَفْعٍ وَقِيَامٍ وَقُعُودٍ وَيُسَلِّمُ عَنْ يَمِينِهِ وَعَنْ شِمَالِهِ السَّلاَمُ عَلَيْكُمْ وَرَحْمَةُ اللَّهِ حَتَّى يُرَى بَيَاضُ خَدِّهِ قَالَ وَرَأَيْتُ أَبَا بَكْرٍ وَعُمَرَ ؓ يَفْعَلاَنِ ذَلِكَ
