Narrated Anas ibn Malik: When the people of the Yemen came, the Messenger of Allah said: The people of the Yemen have come to you and they are first to shake hands.
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، حَدَّثَنَا حُمَيْدٌ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ لَمَّا جَاءَ أَهْلُ الْيَمَنِ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " قَدْ جَاءَكُمْ أَهْلُ الْيَمَنِ وَهُمْ أَوَّلُ مَنْ جَاءَ بِالْمُصَافَحَةِ " .
