"I said to Ibn 'Umar: "Tell me about the prayer of the Messenger of Allah ﷺ; how was it?" He mentioned the takbir and he mentioned: As-salamu 'alaykum wa rahmatullah (peace be upon you and the mercy of Allah) to his right and: As-salamu 'alaykum (peace be upon you) to his left." (Using translation from Nasāʾī 1321)   

أَخْبِرْنِي عَنْ صَلَاةِ رَسُولِ اللهِ ﷺ كَيْفَ كَانَتْ؟ قَالَ «فَذَكَرَ التَّكْبِيرَ يَعْنِي وَذَكَرَ السَّلَامَ عَلَيْكُمْ وَرَحْمَةَ اللهِ عَنْ يَمِينِهِ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ عَنْ يَسَارِهِ»  

The Prophet ﷺ said: "It is as if I can see the whiteness of his cheek, saying to his right: As-salamu 'alaykum wa rahmatullah (peace be upon you and the mercy of Allah) and to his left: As-salamu 'alaykum wa rahmatullah (peace be upon you and the mercy of Allah)." (Sahih (Using translation from Nasāʾī 1322)  

عَنِ النَّبِيِّ ﷺ قَالَ كَأَنِّي أَنْظُرُ إِلَى بَيَاضِ خَدِّهِ عَنْ يَمِينِهِ «السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ» وَعَنْ يَسَارِهِ «السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ»  

"The Messenger of Allah ﷺ used to say the salam to his right so that the whiteness of his cheek could be seen, and to his left so that the whiteness of his cheek could be seen." (Using translation from Nasāʾī 1323)  

كَانَ رَسُولُ اللهِ ﷺ «يُسَلِّمُ عَنْ يَمِينِهِ حَتَّى يَبْدُوَ بَيَاضَ خَدِّهِ وَعَنْ يَسَارِهِ حَتَّى يَبْدُوَ بَيَاضَ خَدِّهِ»  

The Prophet ﷺ used to say salam to his right and to his left: As-salamu 'alaykum wa rahmatullah, as-salamu alaykum wa rahmatullah (peace be upon you and the mercy of Allah, peace be upon you and the mercy of Allah) until the whiteness of his cheek could be seen from here, and the whiteness of his cheek from here. (Using translation from Nasāʾī 1324)  

عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ يُسَلِّمُ عَنْ يَمِينِهِ وَعَنْ يَسَارِهِ «السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ» حَتَّى يُرَى بَيَاضُ خَدِّهِ مِنْ هَاهُنَا وَبَيَاضُ خَدِّهِ مِنْ هَاهُنَا  

The Messenger of Allah ﷺ used to say salam to his right:As-salamu 'alaykum wa rahmatullah (peace be upon you and the mercy of Allah) , until the whiteness of his right cheek could be seen, and to his left: As-salamu 'alaykum wa rahmatullah (peace be upon you and the mercy of Allah) until the whiteness of his left cheek could be seen. (Using translation from Nasāʾī 1325)  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يُسَلِّمُ عَنْ يَمِينِهِ «السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ» حَتَّى يُرَى بَيَاضُ خَدِّهِ الْأَيْمَنِ وَعَنْ يَسَارِهِ «السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللهِ» حَتَّى يُرَى بَيَاضُ خَدِّهِ الْأَيْسَرِ
