Compiled by Imam Muhammad al-Bukhari
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا غُنْدَرٌ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، قَالَ سَمِعْتُ الْبَرَاءَ بْنَ عَازِبٍ ـ رضى الله عنهما ـ قَالَ أَوَّلُ مَنْ قَدِمَ عَلَيْنَا مُصْعَبُ بْنُ عُمَيْرٍ وَابْنُ أُمِّ مَكْتُومٍ، وَكَانَا يُقْرِئَانِ النَّاسَ، فَقَدِمَ بِلاَلٌ وَسَعْدٌ وَعَمَّارُ بْنُ يَاسِرٍ، ثُمَّ قَدِمَ عُمَرُ بْنُ الْخَطَّابِ فِي عِشْرِينَ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم ثُمَّ قَدِمَ النَّبِيُّ صلى الله عليه وسلم، فَمَا رَأَيْتُ أَهْلَ الْمَدِينَةِ فَرِحُوا بِشَىْءٍ فَرَحَهُمْ بِرَسُولِ اللَّهِ صلى الله عليه وسلم، حَتَّى جَعَلَ الإِمَاءُ يَقُلْنَ قَدِمَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَمَا قَدِمَ حَتَّى قَرَأْتُ {سَبِّحِ اسْمَ رَبِّكَ الأَعْلَى} فِي سُوَرٍ مِنَ الْمُفَصَّلِ.
The first people who came to us (in Medina) were Mus`ab bin `Umar and Ibn Um Maktum who were teaching Qur'an to the people. Then their came Bilal. Sa`d and `Ammar bin Yasir. After that `Umar bin Al-Khattab came along with twenty other companions of the Prophet. Later on the Prophet (ﷺ) himself (to Medina) and I had never seen the people of Medina so joyful as they were on the arrival of Allah's Apostle, for even the slave girls were saying, "Allah's Messenger (ﷺ) has arrived!" And before his arrival I had read the Sura starting with:-- "Glorify the Name of your Lord, the Most High" (87.1) together with other Suras of Al-Mufassal.
