[Machine] Regarding the prayer of the Messenger of Allah ﷺ , he used to say "Allahu Akbar" (Allah is the greatest) every time he raised his hands and every time he placed them in the bowing and prostration positions. And when he finished, he said "As-Salamu Alaykum wa Rahmatullahi" (peace and mercy of Allah be upon you) twice, first to his right and then to his left.
عَنْ صَلَاةِ رَسُولِ اللهِ ﷺ فَقَالَ كَانَ إِذَا صَلَّى قَالَ اللهُ أَكْبَرُ كُلَّمَا رَفَعَ وَكُلَّمَا وَضَعَ فِي الرُّكُوعِ وَالسُّجُودِ وَإِذَا انْصَرَفَ قَالَ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ عَنْ يَمِينِهِ وَعَنْ يَسَارِهِ
