Hadith 13334

(حديث مرفوع) حَدَّثَنَا يَحْيَى بْنُ إِسْحَاقَ ، قَالَ : أَخْبَرَنَا يَحْيَى بْنُ أَيُّوبَ ، حَدَّثَنَا حُمَيْدٌ الطَّوِيلُ ، قَالَ : سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ، يَقُولُ : قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " سَيَقْدَمُ عَلَيْكُمْ قَوْمٌ ، هُمْ أَرَقُّ قُلُوبًا لِلْإِسْلَامِ مِنْكُمْ " ، قَالَ : فَقَدِمَ الْأَشْعَرِيُّونَ مِنْهُمْ أَبُو مُوسَى الْأَشْعَرِيُّ ، فَلَمَّا قَرُبُوا مِنَ الْمَدِينَةِ ، جَعَلُوا يَرْتَجِزُونَ ، وَجَعَلُوا يَقُولُونَ : غَدًا نَلْقَى الْأَحِبَّةَ مُحَمَّدًا وَحِزْبَهُ قَالَ : وَكَانَ هُمْ أَوَّلَ مَنْ أَحْدَثَ الْمُصَافَحَةَ .
It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Such people will come to you whose hearts will be softer than yours." Accordingly, once the Ash'aris came, among whom was Hazrat Abu Musa Ash'ari (may Allah be pleased with him) as well. When they reached near Madinah Munawwarah, they began to recite these rajaz verses: "Tomorrow we will meet our friends, that is, Muhammad (peace and blessings be upon him) and his companions." And these were the first people who established the practice of shaking hands.
