“The Messenger of Allah ﷺ used to straighten the rows until he made them like a spear or an arrow-shaft. Once he saw a man’s chest (sticking out) so the Messenger of Allah ﷺ said: ‘Make your rows straight or Allah will create division among you.’”  

ابن ماجة:٩٩٤حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ حَدَّثَنَا سِمَاكُ بْنُ حَرْبٍ

أَنَّهُ سَمِعَ النُّعْمَانَ بْنَ بَشِيرٍ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ يُسَوِّي الصَّفَّ حَتَّى يَجْعَلَهُ مِثْلَ الرُّمْحِ أَوِ الْقِدْحِ قَالَ فَرَأَى صَدْرَ رَجُلٍ نَاتِئًا فَقَالَ رَسُولُ اللَّهِ سَوُّوا صُفُوفَكُمْ أَوْ لَيُخَالِفَنَّ اللَّهُ بَيْنَ وُجُوهِكُمْ

ذِكْرُ الْأَمْرِ بِتَسْوِيَةِ الصُّفُوفِ حَذَرَ مُخَالَفَةِ الْوُجُوهِ عِنْدَ تَرْكِهِ
