"O Messenger of Allah! Should we bow to one another?" He said: "No." We said: "Should we embrace one another?" He said: "No, but shake hands with one another."  

قُلْنَا يَا رَسُولَ اللَّهِ أَيَنْحَنِي بَعْضُنَا لِبَعْضٍ قَالَ لاَ قُلْنَا أَيُعَانِقُ بَعْضُنَا بَعْضًا قَالَ لاَ وَلَكِنْ تَصَافَحُوا  

"There are no two Muslims who meet and shake hands, but they will be forgiven before they part."  

قَالَ رَسُولُ اللَّهِ ﷺ مَا مِنْ مُسْلِمَيْنِ يَلْتَقِيَانِ فَيَتَصَافَحَانِ إِلاَّ غُفِرَ لَهُمَا قَبْلَ أَنْ يَتَفَرَّقَا
