"Messenger of Allah would straighten our lines. One day he came out and saw a man whose chest was protruding from the people, so he said: 'You must straighten your lines, or Allah will cause disagreement to occur among your faces."
كَانَ رَسُولُ اللَّهِ ﷺ يُسَوِّي صُفُوفَنَا فَخَرَجَ يَوْمًا فَرَأَى رَجُلاً خَارِجًا صَدْرُهُ عَنِ الْقَوْمِ فَقَالَ لَتُسَوُّنَّ صُفُوفَكُمْ أَوْ لَيُخَالِفَنَّ اللَّهُ بَيْنَ وُجُوهِكُمْ قَالَ وَفِي الْبَابِ عَنْ جَابِرِ بْنِ سَمُرَةَ وَالْبَرَاءِ وَجَابِرِ بْنِ عَبْدِ اللَّهِ وَأَنَسٍ وَأَبِي هُرَيْرَةَ وَعَائِشَةَ
