سَمِعْتُ النُّعْمَانَ بْنَ بَشِيرٍ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ يُسَوِّي صُفُوفَنَا حَتَّى كَأَنَّمَا يُسَوِّي بِهَا الْقِدَاحَ حَتَّى رَأَى أَنَّا قَدْ عَقَلْنَا عَنْهُ ثُمَّ خَرَجَ يَوْمًا فَقَامَ حَتَّى كَادَ يُكَبِّرُ فَرَأَى رَجُلاً بَادِيًا صَدْرُهُ مِنَ الصَّفِّ فَقَالَ عِبَادَ اللَّهِ لَتُسَوُّنَّ صُفُوفَكُمْ أَوْ لَيُخَالِفَنَّ اللَّهُ بَيْنَ وُجُوهِكُمْ

سَمِعْتُ النُّعْمَانَ بْنَ بَشِيرٍ يَقُولُ كَانَ رَسُولُ اللهِ ﷺ يُسَوِّي الصَّفَّ حَتَّى يَجْعَلَهُ مِثْلَ الرُّمْحِ أَوِ الْقَدَحِ قَالَ فَرَأَى صَدْرَ رَجُلٍ نَاتِئًا فَقَالَ رَسُولُ اللهِ ﷺ يَا عِبَادَ اللهِ لَتُسَوُّنَّ صُفُوفَكُمْ أَوْ لَيُخَالِفَنَّ اللهُ بَيْنَ وُجُوهِكُمْ
