The Book of Greetings
The Excellence of Shaking Hands When Greeting Someone
وَعَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: لَمَّا جَاءَ أَهْلُ الْيَمَنِ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ : “قَدْ جَاءَكُمْ أَهْلُ الْيَمَنِ، وَهُمْ أَوَّلُ مَنْ جَاءَ بِالْمُصَافَحَةِ" ((رَوَاهُ أَبُو دَاوُدَ بِإِسْنَادٍ صَحِيح)).
Anas (May Allah be pleased with him) reported: When the people of Yemen came, the Messenger of Allah (ﷺ) said, "The people of Yemen have visited you. They are the first to introduce the tradition of handshaking." [Abu Dawud].
