Hadith 5956
Al-Bara' said: The first of the companions of God's messenger to come to us were Mus'ab b. `Umair and Ibn Umm Maktum who began to teach us the Quran[1]. Then `Ammar,[2] Bilal[3] and Sa'd[4] came. Then `Umar b. al-Khattab came with twenty of the Prophet's companions. Then the Prophet came, and I never saw the people of Medina so happy about anything as they were about him. I even saw the little girls and boys saying, "This is God's messenger who has come." By the time he came I had learned "Glorify the name of your most high Lord"[5] along with similar suras from al-Mufassal. 1. These two were sent to Medina before the Hijra to teach the people who had sworn allegiance to the Prophet. 2. 'Ammar b. Yasir. 3. Bilal b. Rabah. 4. Sa'd b. Abu Waqqe. 5. Quran:87 Bukhari transmitted it.
عَن الْبَراء قَالَ: أَوَّلُ مَنْ قَدِمَ عَلَيْنَا مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مُصْعَبُ بْنُ عُمَيْرٍ وَابْنُ أُمِّ مَكْتُومٍ فَجَعَلَا يُقْرِآنِنَا الْقُرْآنَ ثُمَّ جَاءَ عَمَّارٌ وَبِلَالٌ وَسَعْدٌ ثُمَّ جَاءَ عُمَرُ بْنُ الْخَطَّابِ فِي عِشْرِينَ مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ثُمَّ جَاءَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَمَا رَأَيْتُ أَهْلَ الْمَدِينَةِ فَرِحُوا بِشَيْءٍ فَرَحَهُمْ بِهِ حَتَّى رَأَيْتُ الْوَلَائِدَ وَالصِّبْيَانَ يَقُولُونَ: هَذَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَدْ جَاءَ فَمَا جَاءَ حَتَّى قرأتُ: [سبِّح اسْم ربِّك الْأَعْلَى] فِي سُوَرٍ مِثْلِهَا مِنَ الْمُفَصَّلِ. رَوَاهُ البُخَارِيّ
