The first people who came to us (in Medina) were Musʿab bin ʿUmar and Ibn Um Maktum who were teaching Qur'an to the people. Then their came Bilal. Saʿd and ʿAmmar bin Yasir. After that ʿUmar 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, "Messenger of Allah 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.  

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 ﷺ ثُمَّ قَدِمَ النَّبِيُّ ﷺ فَمَا رَأَيْتُ أَهْلَ الْمَدِينَةِ فَرِحُوا بِشَىْءٍ فَرَحَهُمْ بِرَسُولِ اللَّهِ ﷺ حَتَّى جَعَلَ الإِمَاءُ يَقُلْنَ قَدِمَ رَسُولُ اللَّهِ ﷺ فَمَا قَدِمَ حَتَّى قَرَأْتُ {سَبِّحِ اسْمَ رَبِّكَ الأَعْلَى} فِي سُوَرٍ مِنَ الْمُفَصَّلِ  

The first of the companions of the Prophet ﷺ who came to us (in Medina), were Musʿab bin ʿUmar and Ibn Um Maktum, and they started teaching us the Qur'an. Then came ʿAmmar, Bilal and Saʿd. Afterwards ʿUmar bin Al-Kkattab came along with a batch of twenty (men): and after that the Prophet ﷺ came. I never saw the people of Medina so pleased with anything as they were with his arrival, so that even the little boys and girls were saying, "This is Messenger of Allah ﷺ who has come." He (the Prophet ﷺ ) did not come (to Medina) till I had learnt Surat Al-Ala and also other similar Suras.  

أَوَّلُ مَنْ قَدِمَ عَلَيْنَا مِنْ أَصْحَابِ النَّبِيِّ ﷺ مُصْعَبُ بْنُ عُمَيْرٍ وَابْنُ أُمِّ مَكْتُومٍ فَجَعَلاَ يُقْرِئَانِنَا الْقُرْآنَ ثُمَّ جَاءَ عَمَّارٌ وَبِلاَلٌ وَسَعْدٌ ثُمَّ جَاءَ عُمَرُ بْنُ الْخَطَّابِ فِي عِشْرِينَ ثُمَّ جَاءَ النَّبِيُّ ﷺ فَمَا رَأَيْتُ أَهْلَ الْمَدِينَةِ فَرِحُوا بِشَىْءٍ فَرَحَهُمْ بِهِ حَتَّى رَأَيْتُ الْوَلاَئِدَ وَالصِّبْيَانَ يَقُولُونَ هَذَا رَسُولُ اللَّهِ قَدْ جَاءَ فَمَا جَاءَ حَتَّى قَرَأْتُ {سَبِّحِ اسْمَ رَبِّكَ الأَعْلَى} فِي سُوَرٍ مِثْلِهَا  

[Machine] The first people to arrive in the city from the companions of the Messenger of Allah ﷺ were Mus'ab bin Umair and Ibn Umm Maktum, and they used to teach the people. Then Bilal, Saad, and Ammar bin Yasir arrived, followed by Umar bin Al-Khattab, who was the twentieth companion of the Messenger of Allah ﷺ . Then the Messenger of Allah ﷺ arrived, and I have never seen the people of the city so happy as they were upon the arrival of the Messenger of Allah ﷺ . Even the slave women used to say, "The Messenger of Allah ﷺ has arrived." He said, "Then when he arrived, I heard him reciting, "Glorify the Name of your Lord, the Most High" in a voice clear and distinct."  

كَانَ أَوَّلَ مَنْ قَدِمَ الْمَدِينَةَ مِنْ أَصْحَابِ رَسُولِ اللهِ ﷺ مُصْعَبُ بْنُ عُمَيْرٍ وَابْنُ أُمِّ مَكْتُومٍ فَكَانُوا يُقْرِئُونَ النَّاسَ قَالَ ثُمَّ قَدِمَ بِلَالٌ وَسَعْدٌ وَعَمَّارُ بْنُ يَاسِرٍ ثُمَّ قَدِمَ عُمَرُ بْنُ الْخَطَّابِ فِي عِشْرِينَ مِنْ أَصْحَابِ رَسُولِ اللهِ ﷺ ثُمَّ قَدِمَ رَسُولُ اللهِ ﷺ فَمَا رَأَيْتُ أَهْلَ الْمَدِينَةِ فَرِحُوا بِشَيْءٍ فَرَحَهُمْ بِرَسُولِ اللهِ ﷺ قَالَ حَتَّى جَعَلَ الْإِمَاءُ يَقُلْنَ قَدِمَ رَسُولُ اللهِ ﷺ قَالَ فَمَا قَدِمَ حَتَّى قَرَأْتُ سَبِّحْ اسْمَ رَبِّكَ الْأَعْلَى فِي سُوَرٍ مِنَ الْمُفَصَّلِ  

"أَوَّلُ مَنْ قَدِمَ عَلَيْنَا مِنْ أَصْحَاب رَسُولِ الله ﷺ مُصْعَبُ بْنُ عُمَيْرٍ، وَابْنُ أُمِّ مَكْتُومٍ، فَجَعَلَا يُقْرِئَانِ النَّاس القُرَآنَ، ثُمَّ جَاءَ عَمَّار وَبِلَالٌ وَسَعْدٌ، ثُمَّ جَاءَ عُمَرُ بْنُ الخَطَّابِ فِي عِشْرِينَ رَاكبًا، ثُمَّ جَاءَ رَسُولُ الله ﷺ فَمَا رَأَيْتُ أَهْلَ الْمَدِينَةِ

فَرِحُوا بِشَيءٍ قط فَرَحهُمْ بِهِ، قال: فما قدم حتى قرأت: "سبح اسم ربك الأعلى" في سورٍ مِنَ المفصل".
