ذِكْرُ مَا يَعْمَلُ الْمُصَلِّي فِي رَدِّ السَّلَامِ إِذَا سُلِّمَ عَلَيْهِ فِي ذَلِكَ الْوَقْتِ
"I passed by the Messenger of Allah ﷺ when he was praying, and greeted him with Salam. He returned my greeting with a gesture, or maybe it was just with his finger." (Using translation from Nasāʾī 1186)
«مَرَرْتُ بِرَسُولِ اللَّهِ ﷺ وَهُوَ يُصَلِّي فَسَلَّمْتُ عَلَيْهِ فَرَدَّ عَلَيَّ إِشَارَةً » وَلَا أَعْلَمُ إِلَّا أَنَّهُ قَالَ « بِإِصْبَعِهِ»
