I asked Anas, "Was it a custom of the companions of the Prophet ﷺ to shake hands with one another?" He said, "Yes."
قُلْتُ لأَنَسٍ أَكَانَتِ الْمُصَافَحَةُ فِي أَصْحَابِ النَّبِيِّ ﷺ قَالَ نَعَمْ
that he asked Anas bin Malik: "Did the Companions of the Messenger of Allah ﷺ use to shake each other's hand?" He said, "Yes."
قُلْتُ لأَنَسِ بْنِ مَالِكٍ هَلْ كَانَتِ الْمُصَافَحَةُ فِي أَصْحَابِ رَسُولِ اللَّهِ ﷺ قَالَ نَعَمْ
ذِكْرُ إِبَاحَةِ الْمُصَافَحَةِ لِلْمُسْلِمِينَ عِنْدَ السَّلَامِ
that he asked Anas bin Malik: "Did the Companions of the Messenger of Allah ﷺ use to shake each other's hand?" He said, "Yes." (Using translation from Tirmidhī 2729)
قُلْتُ لِأَنَسِ بْنِ مَالِكٍ أَكَانَتِ الْمُصَافَحَةُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ؟ قَالَ «نَعَمْ»
