Arabic (Original)
حَدَّثَنَا حُسَيْنُ بْنُ عَلِيٍّ عَنْ زَائِدَةَ عَنْ سِمَاكٍ عَنِ النُّعْمَانِ بْنِ بَشِيرٍ قَالَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُسَوِّينَا فِي الصُّفُوفِ حَتَّى كَأَنَّمَا يُحَاذِي بِنَا الْقِدَاحَ فَلَمَّا أَرَادَ أَنْ يُكَبِّرَ رَأَى رَجُلًا شَاخِصًا صَدْرُهُ فَقَالَ لَتُسَوُّنَّ صُفُوفَكُمْ أَوْ لَيُخَالِفَنَّ اللَّهُ بَيْنَ وُجُوهِكُمْ.
English Translation
Husayn b. Ali told us, from Za'ida, from Simak, from al-Nu'man b. Bashir, who said: The Messenger of Allah, peace and blessings be upon him, used to straighten us in the rows until it was as if he aligned us like arrows. Then when he wanted to say the opening takbir, he saw a man whose chest was protruding, so he said: "You shall straighten your rows, or Allah will surely turn your faces against one another."
