وعن النعمان بن بشير ﵄، قَالَ: سمعت رَسُول اللهِ - ﷺ - يقول: «لَتُسَوُّنَّ صُفُوفَكُمْ، أوْ لَيُخَالِفَنَّ اللَّهُ بَيْنَ وُجُوهِكُمْ». متفقٌ عَلَيهِ. وفي رواية لمسلم: أنَّ رَسُول اللهِ - ﷺ - كَانَ يُسَوِّي صُفُوفَنَا، حَتَّى كَأنَّمَا يُسَوِّي بِهَا القِدَاحَ حَتَّى رَأى أنَّا قَدْ عَقَلْنَا عَنْهُ، ثُمَّ خَرَجَ يَومًا فَقَامَ حَتَّى كَادَ يُكَبِّرُ، فَرَأى رَجُلًا بَادِيًا صَدْرُهُ مِنَ الصَّفِّ، فَقَالَ: «عِبَادَ اللهِ، لتُسَوُّنَّ صُفُوفَكُمْ، أو لَيُخَالِفَنَّ اللهُ بَيْنَ وُجُوهِكُمْ».
Al-Nuʿmān ibn Bashīr (may Allah be pleased with them both) reported: I heard the Messenger of Allah (peace and blessings be upon him) say, "You shall surely straighten your rows, or Allah will surely set your faces in opposition to one another." Agreed upon (al-Bukhārī and Muslim). In a narration of Muslim: The Messenger of Allah (peace and blessings be upon him) used to straighten our rows until it was as though he were straightening arrow-shafts with them, until he saw that we had grasped this from him. Then one day he came out and stood, and was about to say the takbīr, when he saw a man whose chest was protruding from the row, so he said, "Servants of Allah, you shall surely straighten your rows, or Allah will surely set your faces in opposition to one another."
