"When the Prophet ﷺ would receive a man to shake hands with him,he would not remove his hand until he [the man]removed his, and he would not turn his face away from his face until the man turned and he would not be seen advancing his knees before one sitting with him."  

كَانَ النَّبِيُّ ﷺ إِذَا اسْتَقْبَلَهُ الرَّجُلُ فَصَافَحَهُ لاَ يَنْزِعُ يَدَهُ مِنْ يَدِهِ حَتَّى يَكُونَ الرَّجُلُ الَّذِي يَنْزِعُ وَلاَ يَصْرِفُ وَجْهَهُ عَنْ وَجْهِهِ حَتَّى يَكُونَ الرَّجُلُ هُوَ الَّذِي يَصْرِفُهُ وَلَمْ يُرَ مُقَدِّمًا رُكْبَتَيْهِ بَيْنَ يَدَىْ جَلِيسٍ لَهُ قَالَ هَذَا حَدِيثٌ غَرِيبٌ  

"When the Prophet ﷺ would receive a man to shake hands with him,he would not remove his hand until he [the man]removed his, and he would not turn his face away from his face until the man turned and he would not be seen advancing his knees before one sitting with him." (Using translation from Tirmidhī 2490)   

كَانَ رَسُولُ اللهِ ﷺ إِذَا صَافَحَ أَوْ صَافَحَهُ الرَّجُلُ لَا يَنْزِعُ يَدَهُ مِنْ يَدِهِ حَتَّى يَكُونَ الرَّجُلُ يَنْزِعُ فَإِنِ اسْتَقْبَلَهُ بِوَجْهِهِ لَا يَصْرِفُهُ عَنْهُ حَتَّى يَكُونَ الرَّجُلُ يَنْصَرِفُ وَلَمْ يَرُدَّ مُقَدِّمًا رُكْبَتَيْهِ بَيْنَ يَدَيْ جَلِيسٍ لَهُ
