«أَوَّلُ مَنْ أَفْشَى الْقُرْآنَ مِنْ فِي رَسُولِ اللهِ ﷺ عَبْدُ اللهِ بْنُ مَسْعُودٍ وَأَوَّلُ مَنْ بَنِي مَسْجِدًا يُصَلَّى فِيهِ عَمَّارُ بْنُ يَاسِرٍ وَأَوَّلُ مَنْ أَذَّنَ بِلَالٌ وَأَوَّلُ مَنْ غَدَا بِهِ فَرَسُهُ فِي سَبِيلِ اللهِ الْمِقْدَادُ بْنُ الْأَسْوَدِ وَأَوَّلُ مَنْ رَمَى فِي سَبِيلِ اللهِ سَعْدٌ وَأَوَّلُ مَنْ قُتِلَ مِنَ الْمُسْلِمِينَ يَوْمَ بَدْرٍ مَهْجَعُ مَوْلَى عُمَرَ بْنِ الْخَطَّابِ وَأَوَّلُ حَيٍّ أَلِفُوا مَعَ رَسُولِ اللهِ ﷺ جُهَيْنَةُ وَأَوَّلُ مَنْ أَدَّوُا الصَّدَقَةَ طَائِعِينَ مِنْ قِبَلِ أَنْفُسِهِمْ بَنُو عُذْرَةَ بْنِ سَعْدٍ»
