When we would pray behind the Messenger of Allah ﷺ, we liked to be on his right side. He (the Prophet) would sit turning his face towards us (and back towards the Ka'bah) ﷺ.  

أبو داود:٦١٥ – حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ حَدَّثَنَا أَبُو أَحْمَدَ الزُّبَيْرِيُّ حَدَّثَنَا مِسْعَرٌ عَنْ ثَابِتِ بْنِ عُبَيْدٍ عَنْ عُبَيْدِ بْنِ الْبَرَاءِ عَنِ الْبَرَاءِ بْنِ عَازِبٍ قَالَ

كُنَّا إِذَا صَلَّيْنَا خَلْفَ رَسُولِ اللَّهِ ﷺ أَحْبَبْنَا أَنْ نَكُونَ عَنْ يَمِينِهِ فَيُقْبِلُ عَلَيْنَا بِوَجْهِهِ ﷺ
